The experience of Dr. Martinez Gomez in the field of metalurgy and the interest in innovate the industry led to the creation of a technology-base company with significant growth.



Making available the most advanced industrial sectors to maintain the integrity of pipes, tanks, docks and other infrastructures threatened by corrosion, allowed Dr. Lorenzo Martinez Gomez, researcher at the Institute of Physics of the UNAM, founded technology-based company with signigicant expansion since 1996.


“The motivation to form the company emerges from my experience in the field of metallurgy and metal corrosion for 35 years,” emphasizes. After having a very successful academic career and supported by the UNAM, Dr. Martinez Gomez saw the importanceof transferring knowledge to industrial solutions.


His entrepreneurship let to the opening of the company Corrosion and Protection S.A. of C.V., located in Cuernavaca. The success and acceptance of the services offered by the entrepreneur scientist have allowed the establishment of two engineering centers in Mexico City, one in Beracruz and another in Villahermosa.


Likewise, it has achieved its expansion to Ecuador, where it serves the needs of the petrol fields in the Amazon since 2010; in Guatemala, it is responsible for port facilities and pipeline systems since 2007 and it provides international services through an office installed in Houston, Texas, in United States of America.


In this context, Dr. Martinez Gomez reported that in the country, a big amount of resources are lost due to the disqualification of work because of corrosion, as in the case of transport of hydrocarbons by duct (considered the circulatory system of energy country), potable water systems and marine facilities.


“However, the problem is controllable by applying engineering knowledge. The external part of the infrastructure is protected with coatings and it is submerged to electric polarization. Likewise, sometimes it is necessary to inject corrosion inhibitors, which are molecules capable of adhering to the metal surface to protect it,” explains the researcher.


Notably, the company Corrosion and Protection grew in the context of a solif training program for specialists to create their own leaders and train engineers from industry, government and other sectors of society.


“The firm’s success is also due to the corrosion control is a service virtually abandoned in Mexico, so when establishing ourselves and offering our solutions, we could have a significant growth. Today, we handle from 100 to 150 annual projects of corrosion control,” he says.


Through more than a dozen research projects, the brand Corrosion and Protection has served companies and institutions. Sometimes, it has managed federal funds from the National Council for Science and Technology (CONACYT), including projects SENER Conacyt Hydrocarbons; and in the states of Colima, Guerrero, Campeche and Morelos in the context of FOMIX and Pro-Innova funds.


Corrosion and Protection has kept a strong quality program under ISO 9002 certification granted in 2010. Its strength is supported on the work developed, technological development for corrosion control and integrity management for companies such as Pemez, CFE, Auxiliary Airports and Services, ICA Fluor, China Harbour Engineering Company, Electricté in France, Repsol Ecuador and Mexico, Ienova, SEMPRA, GDF Suez, Norpower, Puerto Quetzal-Guatemala, Costa Riva Kativo, Daimer Chrysler, TAMSA, Tradeco, Metrogas, Prazaiz, amon others; and the governments of Morelos, Guerrero and Campeche.

From Ineltec, we recommend to subject any metal piece or material to laboratory tests for checking its resistance to hard external conditions that they will meet and by this way, verify that the pieces are reliable, safe and durable.


In humidostatic chambers, it can be subjected pieces to saturated humidity tests (H.R. 100%).


In Kesternich chambers, the pieces are subjected to an atmosphere of saturated humidity and sulfur dioxide in which it is simulated the acid rain.


In a salt spray chamber, the samples are subjected to salt spray tests, ASTM B117 is one of the most important standards in describing this method.


Finally, the samples or materials (normally metal pieces for automotive sector) which may be subjected to several different environmental conditions should be tested in cyclic corrosion chambers in which different stages are combined (Salt spray – Humidostatic – Climatic (Temperature and Relative Humidity)).

Dreadful sharks will soon have a new enemy to beat: drones. Australia has decided to use unmanned aircrafts to prevent the attacks of these hazardous animals, monitoring their movements to avoid encounter along the way with humans.


The threat of sharks in Australia I more than a reality, since the country has grown from just 3 shark attacks in 2014 along the 2000km of shore, only the state of New South Wales, to experience nothing less than 13 this year. In fact, this February, a tourist from Japan died there because of the attack of one of these animals that bit off both legs.


So, then authorities exclude other options as proactive hunt of sharks, this Australian state government has promoted a program of five years and a cost of 11,5 million dollars which, between others, it includes deployment of drones on the beaches.


Drones, and manned helicopters to a lesser extent, constantly will monitor shore zones and will alert in real time the presence of any anomalies that may be indicative of the presence of sharks in the area. All these data will be received by the local authorities but also by the citizens and tourists, through a mobile app called “SharkSmart”.


Listening stations and sonar buoys

But these are not the only devices that the Australian government will launch in its fight against one of the most dangerous animal in the world. In this regard, authorities will also arise twenty listening stations in areas where sharks pass in greater numbers.


Furthermore, it will be installed a large amount of buoys in the sea equipped with the latest sonar capable of identify sharks. These buoys will be, as well as drones, connected in real time with the monitoring centrals to give warning of “Sharks ahoy” as soon as possible.


Drones on the short, becoming more frequent

The use of unmanned aircrafts in the coast is something increasingly common. The case of Australia, we have to join, for example, initiatives carried out in Chile, where already use drones to help lifeguards on the beaches. The experiment has become even more effective that a drone carrying a lifesaver came long before to give assistance to the victim than a human lifeguard.


In our country, Galicia is promoting a public-private project to promote the use of civilian drones for different tasks such as protecting the green mountains of the region from fire, but also to monitor the shore. Likewise, United States also has numerous projects combining sea and drones, from researching grey whales to control migration flows.

For drones can save life without problems; they must be safe and reliable.


How it is tested the reliability of these devices?


Drones as any other devices who is submitted to environmental conditions and you want to market it in different parts of the world, it is recommend performing tests of all types in laboratory scale to check its resistance and reliability, and its operation is not altered by external agents.


Some examples could be:


- Aging light tests combined with temperature and humidity to check that does not lose its properties when it is exposed to sunlight, temperature and humidity; this type of tests can be done in climatic chambers with UV radiation.


- Tests of IP protection over the housing enclosing all electronic devices. It is testing to check the level of protection that the enclosure has against external agents such as dust or penetration of water droplets that could seriously impair the operation of the electronics. Such tests are performed in rain or dust tightness chambers.


- In the case of drones that are going to be used on the coast, it would be advisable that the different part that compounds it were made resistant to corrosion, especially saline corrosion. These tests are performed in salt spray chambers.
