Mexico.
The National Polytechnic Institute (IPN), through the Surface Engineering Group (GIS), developed the Official Mexican Standard NMX-R-082-SCFI-2016, which determines the cohesion-adhesion during the advanced technical ceramic coating process by tearing-test method.
The Ministry of Economy, through the General Directorate of Standards, published on July 12 in the Official Gazette of the Federation (DOF) the Declaration of Validity of the Mexican Standard, which was prepared and approved by the Technical Committee for National Standardization of Various Industries.
The developers of the Standard are more than 20 researchers and polytechnic specialists with international recognition belonging to the GIS, a group that is a member of the "Thematic Network: Engineering of Surfaces and Thin Layers" of Spain.
This Standard is the first developed by the IPN. It describes a specific method that evaluates adhesion-cohesion in ceramic coatings. Its purpose is to determine the amount of force applied, and to identify a specific, recognizable and defined failure mechanism in the coating-substrate system. The Mexican Standard applies nationwide and is designed to be used in the macro force range, but can be adapted to other parameters.
It is worth mentioning that the GIS was formed at the Higher School of Mechanical and Electrical Engineering (ESIME), Zacatenco Unit, in 2007, with the purpose of strengthening basic and applied research in the surface hardening of metallic materials such as steels, alloys and titanium, through thermochemical treatments that increase the mechanical, physical and chemical surface properties of components used in different industrial sectors.
The Mexican Standard NMX-R-082-SCFI-2016 will enter into force 60 calendar days after the publication of this Declaration of Validity in the DOF.
