The coating production types are as follows:
The supersonic flame spraying flame flow (1100 m/s) speed, the jet particle impact energy is large, the powder oxidation burns is small, and the coating with high density, high bonding strength and excellent comprehensive performance can be obtained. Bonding strength: ≥80MPa; porosity: ≤1%; coating thickness: 0.1-0.3mm; roughness of unprocessed surface: Ra3.2-6.3
Spraying is a kind of surface strengthening technology, and it has always been a new technology project to be promoted in my country. It can be used to repair the old and waste in equipment maintenance, so that the scrapped and processed out-of-tolerance mechanical parts can be "resurrected", and it can also be strengthened and pre-protected in the manufacture of new products to "extend life." After being processed by thermal spraying process, the service life of mechanical parts can be increased several times or several tens of times.
The spray coating is as follows:
Name Performance and application Microhardness Operating temperature
WC-12Co excellent wear and corrosion resistance 950-1350 500℃
WC-10Co-4Cr has good corrosion resistance and wear resistance 1000-1400 500℃
WC-10Ni excellent corrosion resistance and impact toughness 900-12 500℃
WC-17Co excellent bonding strength and impact toughness 900-12 500℃
Cr3C2-NiCr Excellent resistance to high temperature and abrasion resistance 850-1100 870℃
Arc spray zinc, aluminum spray, stainless steel, etc.
