Through participating in the thermal spraying conference, we more intuitively understand the thermal spraying layer customers with diamond grinding wheel grinding process of thermal spraying layer, from the thermal spraying materials, spraying equipment, spraying application and so on to make a few summaries：
1. Coating material:
(1) Self-binding type. With metal aluminum, titanium, zirconium, chromium and their alloy materials as the core, outer coated with nickel or cobalt.
(2) Wear resistance type: WC, TiC, BN, Cr3C2, SiC, TiN, diamond as the core, its surface is covered with metal nickel,cobalt, copper or alloy Ni - Cr - Al, Co - Cr - Al - Y, etc,can be used to make processing tools or wear resistant coatings. Many of our grinding wheel customers use this process.
2. Application field of thermal spraying coating:
-Aerospace (rocket nozzles,automotive field (Cylinder block, engine block, gas turbine, turbocharger)
-Electrical power generating system
-Oil industry
-Iron and steel metallurgy
-HVOF replaces electroplating
3. Characteristics of thermal spraying layer material:
-High melting point, low thermal conductivity, high thermal expansion coefficient.
-Stable phase structure
-High-temperature oxidation resistance
-Resistance to sulfate and vanadate CMAS
-Resistance of sintered
-Controlled interdiffusion between coating and substrate
-Thermal shock
Thermal spray coating is the most advanced and complex coating system.
