The low melting point of Sn-based Babbitt alloys often causes nozzle clogging in the low-pressure cold gas-dynamic spraying (LPCGDS) process, which impacts the process steadiness and the coating quality. Adding hard particles to the feedstock material el...

One of the main causes of hip prostheses failure is the premature wear of their components. Multi-directional motion or ?cross-shear? motion has been identified as one of the most significant factors affecting the wear rate of UHMWPE in total hip joint r...
