A thin layer of metal foil bonded to a substrate to form the conductive PCB pattern.

A method of applying a layer of metal over another metal whereby the junction of the two metals is continuously welded.

A relatively thick layer of ( 0.04" ) of different material applied by surface welding for the purpose of improving corrosion or heat resistance.

Application of a stainless steel coating to a lower-alloy steel by means of pouring, welding, or coating to increase corrosion resistance at a lower cost than using steel exclusively.

The application of a thick (generally above 1mm) coating which melts or diffuses into the substrate. Processes include weld cladding and plasma transferred arc (PTA).

The application of a thin coat of stainless steel to another metal in order to increase corrosion resistance.
