coating of insulating materials supplier will introduce to you: plasma spraying technology is the most common process for insulating coating of electric drive system. Plasma spraying technology uses the plasma arc driven by direct current as the heat source to heat ceramics, alloys, metals and other materials to a molten or semi-molten state, and sprays them on the surface of the pretreated workpiece at high speed to form a firmly adhered surface layer.
After the powder feeding gas pushes the powder particles into the plasma jet, the particles are rapidly heated and accelerated to form a molten or semi-molten particle beam, which hits the surface of the pretreated substrate, deforms and solidifies on the surface of the substrate.
The coating of insulating materials supplier tells you: the later molten particles are laminated on the previously solidified particles, and the final coating is a layered tissue structure in which countless sheets of particles are interlaced and stacked together in waves. The combination of the coating and the surface of the substrate is mainly based on mechanical bonding, so there are inevitably pores between particles.
