The synthesis of ceramic pigments is conventionally carried out at a high temperature (not less than 1,200 °C). Its reduction implies using mineralizing additives, which have a different mechanism of action on the starting components of pigment char...

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...
