- Mechanical and tribological properties of tungsten carbide sputtered coatings J. Esteve E. Martinez C. Rincon G. Zambrano P. Prieto H. Galindo Física, Astronomía y Matemáticas Tungsten Carbide (WC) hard coatings have been obtained on steel substrates by r.f. magnetron sputtering process. Two layer coatings have been deposited in order to improve adhesion on steel. The lower layer was tungsten metal and the upper WC layer was obtained by reactive sputtering of the tungsten target in Ar and methane gas mixture. AES and SIMS confirmed that the WC layer composition depends on the reactive sputtering gas composition. Film microhardness were measured by microindentation and coating adhesion by microscratch. Measurement results showed that high hardness coatings can be prepared at a relative low temperature and that good adhesion on steel is achieved with the two layer coating. Nanowear measurements showed a noticeable dependence of this applied functional property on the coating compositions 1999 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94200972 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
