Wear rate analysis of a coating

The oil industry has many challenges, among the main ones are the development of materials with resistance to corrosion and wear. The objectives of this work are to obtain a nanometric coating and to analyze its wear rate. The coating was a mixture of 5% WC-CoCr (used in commercial form and milled at times of 3, 6 and 12 hours) in a Ni-Cr matrix. The coating was deposited by HVOF (High Velocity Oxygen Fuel). Tribological, profilometry, roughness, microhardness and Raman tests were performed. The processing of WC-CoCr, in the time of 6 hours, increased the wear resistance, as well as its addition in a Ni-Cr matrix.
