Abstract
The morphology of a WC–17Ni thermal spraying powder has been studied. The structure and element distribution in the powder have been investigated using an SEM with energy dispersive spectroscopic micro analytical facilities. The results show that the, powder particles consist of polycrystalline tungsten carbide particles and homogeneous nominally pure nickel coatings. No intermetallic phases or inter diffusion of tungsten into nickel or nickel into tungsten carbide have been found. The results obtained have been correlated with the structure of the coatings formed after high velocity oxyfuel spraying. PM/0640
