It is used to repair or pre-reinforcement the work pieces with wear resistance and erosion resistance. Such as the wear parts that used in the industries of oil drilling, mine exploitation, engineering machinery.

Surfacing Coating/Spraying/Cladding/Overlaying Technology is one of the crucial technologies to improve the service life of the work pieces. It can be used in the form of special treatment and machining on the surface of the work pieces to improve its wear resistance against abrasion, erosion, corrosion and heat significantly and increase the service life and achieve the repair purpose finally.
