A thermal spray coating made of a metal ceramic, and a thermal spraying powder for obtaining the thermal spray coating.

According to the existing technology shows us, in order to prevent the damage caused by the molten metal, in die casting die cavity surface and roll in a hot dip galvanizing groove surface formation made of metal ceramic thermal spray powder coating.Japan special Kaiping 2004-300555, patent gazette open the hot spraying material for the purpose.
For the formation of metal ceramic thermal spray coating on the surface of the metal substrate, the thermal spray powder, thermal expansion coefficient is less than that of the base material of the thermal expansion coefficient. Therefore, the thermal spray coating may be flaking or cracking. As a result, it may not effectively prevent the substrate damage. Japan Kaiping 2004-277828 patent discloses an intermediate layer positioned between the substrates and thermal spray coating, the thermal expansion coefficient between the coating and the base material of the thermal spray thermal expansion coefficient, in order to prevent the thermal spray coating spalling and cracking. However, this may cause another problem. That is due to the increase of the formation of intermediate steps, makes the cost rise.

Note: thermal spraying coating performance is decided by the spraying material,spraying technology and other factors. Therefore, powder physical properties of spray powder coatings also has certain influence. In addition, some spraying method (especially plasma spray and spray welding process) to produce a variety of harmful factors, so when using this kind of method must take appropriate protective measures.
