Tribological Study of a Bimodal WC-Co Coating Applied by HVOF

Thermal spraying is one of the most versatile techniques that have been used for the application of coatings to protect the wear components by abrasion, adhesion, erosion, corrosion and fatigue. In this article the influence of additions of nanostructured and microstructured powders in the mechanical properties of WC-Co bimodal coatings applied by high speed oxy-fuel (HVOF) was analyzed. The coatings were obtained from a milling process and...
