摘要: In this study, coatings WC-10Co-4Cr and Cr3C2-25NiCr were deposited on the AISI H13 steel by oxy-fuel Thermal spraying (HVOF). This coating increases wear resistance of surfaces subjected to severe conditions, such as: abrasive wear, thermal fatigue plastic deformation. The microstructure, hardness are investigated through friction tests performed a pin-on-disc type tribometer following procedures defined in ASTM G99-04. It was verified that both materials used have high however, sample coated with there greater removal material during test.
