Tungsten Carbide and Tantalum Carbide Coatings on Machining Tools
High speed steel tools for machining were coated with WC and TaC by chemical vapor deposition (CVD), and were used in a high speed milling machine. The physical integrity of the tools coatings were analyzed by scanning electron microscopy at the end of the trials and materials surface roughness were compare in order to predict best behaviour too. These analyses indicate that the deposits form heterogeneous fi lms. The results indicate that the coating made from TaC resist higher attrition than made of WC.
