Tungsten carbides coatings are one of the mo st promising coatings used against wear and corrosion in industry, in particular in aerospace, automation, transportation and power generation system. The paper presents the investigation of WC-Co coatings produced by high velocity oxy- fuel (HVOF) spraying method using two feedstock powders with different particles granulation. The substrate selected for depositions was a C45 steel. The morphology and phases modification of the coatings was analyzed by Scanning Electro...
