Laser cladding utilizes laser as heat source to deposit a thin layer of desired metal on a substrate.

Typical coating materials form: powder and wire.

Typical coating alloys: Ni, Co, Fe base alloy and metal matrix composite with carbides.

Suitable substrate: carbon steel, stainless steel and other alloys.


More resistant to impact: metallurgy bonding

More corrosion resistant: pore free, fully dense

More stable: a high degree of automation, quality control

Applicability: small thermal effect, substrate deformation small, low dilution rate (1-5%)
