Bimetallic barrel is made of a metal material with a certain mechanical strength as the base metal, and in its hole in the face of a composite layer of special alloy material composite layer of the composition of the tube. This layer has a certain thickness and a certain degree of hardness of the alloy protective layer according to the use of working conditions, or have a wear resistance, or has a corrosion resistance, or has both the role of wear and corrosion resistance. Evenly attached to the base metal, and the base metal between the metal interlocked and will not fall off, forming a solid whole - bimetallic barrel. |
