The current study is focused on cermet based WC hard coatings, materials that are extensively used in applications requiring wear resistance. Two different powders WC-20%CrC-7%Ni and WC-10%Co-4%Cr were thermally sprayed on low-carbon steel substrates using the high-velocity oxygen-fuel (HVOF) process. The used powders were spheroidized having the grain sizes in the range of -10+2μm. Both coatings were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) in order to study their morphology and phases. The sliding wear resistance was determined using the pin-on-disk method. Comparative results showed that the WC-CoCr coating has better wear properties than the WC-CrC-Ni coating..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
