Cobalt Base Alloy-Laser Cladding Alloy Powder
Introduction of  Laser Cladding Co Based Powder:
Cobalt base alloys typically contain tungsten and carbon for strengthening. Carbon has low solid solubility in cobalt and therefore, most of it partitions in WC, W2C and M6C or other carbides. These hard phases have a strengthening effect, making such alloys maintain high hardness and strength at temperatures under 800℃. The cobalt-chromium-tungsten-carbon alloys generally have excellent properties to resist high temperature wear, oxidation and thermal fatigue.

Laser Cladding Process Introduction:

Laser Cladding is an alternative to traditional welding and thermal spray. This technology is similar to thermal spray in that it has an energy source to melt the feed stock that is being applied to a substrate. Where it differs is that it uses a concentrated laser beam as the heat source and it melts the substrate that the feed stock is being applied to. This results in a metallurgical bond that has superior bond strength over thermal spray. Additionally the resulting coating is100% dense with no voids or porosity.


Advantages Laser Cladding Process:
One of the advantages of the laser cladding process is the concentrated beam of energy from the laser. It can be focused and concentrated to a very small area and keeps the heat effected zone of the substrate very shallow. This minimizes the chance of cracking, distorting, or changing the metallurgy of the substrate. Additionally the lower total heat minimizes the dilution of the coating with material from the substrate.
