What is Metal Cladding - Process, types, Advantages

Metal cladding is a method of protecting one metal (or composite) by forming a layer of a second metal to its surface by using techniques such as diffusion, deformation and lasers. The advantage of cladding is that the process as well as the material can be chosen as per the needs of the application and the bond strength required.

Honing vs. Lapping, their advantages & limitation. –

The lapping process is more gentle than honing and removes much less surface material. Therefore, the workpiece should be as close as possible to final size — achieved, for example, through double-disk grinding — because lapping typically removes only 0.0005" to 0.005" (0.0127 mm to 0.127 mm) of material.
