The LBP130H plasma spraying equipment developed by the company is a new type of plasma spraying system, which adopts mass flow controller and a new generation of optical fiber controlled inverter power supply as the core configuration system, and is also one of the most popular plasma spraying equipment in the world. Plasma spraying is a technology for material surface strengthening and surface modification, which can make the surface of the substrate have the properties of wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, wear reduction and sealing. The basic principle of plasma spraying technology is to use a plasma arc driven by direct current as a heat source to heat ceramics, alloys, metals and other materials to a molten or semi-molten state, and spray them on the surface of the pretreated workpiece at high speed to form a firmly attached surface layer. Plasma spraying is also used for medical purposes, where a layer of tens of microns is applied to the surface of artificial bones as a way to strengthen artificial bones and enhance their affinity. LBP130H spraying system is a spraying equipment developed on the basis of the introduction, digestion and absorption of foreign advanced equipment and technology, and has a variety of significant characteristics compared with other plasma spraying equipment.
