Significant contribution on corrosion-erosion resistance of Ni3B-TiB2 nanocomposite coating of 1µm of thickness, deposited by DC magnetron Sputtering on stainless steel 304 substrates was studied. Nickel phase (γ Ni) plus Ni3B-TiB2 phases were synthesized previously by Mechanical Alloying (MA). Solid cathode (76.2 mm of diameter and 3 mm of thickness) used to grow thin films was manufactured with the alloyed powders, applying a uniaxial load of 70 MPa at room temperature and sintered at 900° C for two hours. Microstructure and mechanical properties of the coatings were characterized by X-Ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), nanoindentation, and wear test with a ball-on-disc tribometer. Compact coating of Ni3B-TiB2 with a microstructure of prismatic crystals after annealing treatment, showing a uniform coating with good adherence and low friction coefficient of 0.5, correlated with a low roughness of Ra ≈ 0.0439±0.0069 µm. The average hardness of 537.4 HV (5265.0 MPa) and wear coefficient at room temperature of 2.552E-10 m2N-1 correspond with medium-hard phases with an elastic-plastic behavior suitable for fatigue applications. Geothermal fluid modified was synthesized in the lab with NaCl/Na2SO4 to evaluate the corrosion resistance of the films in a standard three electrodes cell, characterizing a corrosion rate of 0.0008 and 0.001 mm*year-1 at 25 and 80°C respectively during 86.4 ks (24 h) of exposition; showing a resistive coating without corrosion products and with good response to the geothermal environment.

Nowadays, modern industry that designs and maintains controlled production processes necessarily involves measurements in their decision making. Metrology, the science of measurement, is present in every aspect of our daily life. In fact, we live with metrology and do not often easily recognize its presence and importance. While technology advances, the presence of Metrology is essential for assistance and support. Metrology would be unfeasible without the existence of qualified personnel in the field of measurements. Metrology education is a key factor for the development of science and technology in any country. Aware of the needs on professional training in the field of metrology, the Polytechnic University at Santa Rosa Jáuregui (UTSRJ), a public university located in the state of Queretaro in Mexico, conducted a survey on the relevance of opening a new educational program. This new program will contribute to the industrial, scientific, technological and social development of the state of Queretaro targeted to impact the rest of the country as well. This study detected the need for trained professionals in the field of metrology, productivity and quality. With the support of representatives from the academic, industrial, research and service sectors, the curriculum design of the Industrial Metrology Engineering was carried out. This new undergraduate program is an innovative and cutting edge educational option designed to satisfy the industrial and social needs which were identified.
