Plasma transferred wire arc thermal spraying - Wikipedia

Plasma transferred wire arc (PTWA) thermal spraying is a thermal spraying process that deposits a coating on the internal surface of a cylindrical surface, or external surface of any geometry. It is predominantly known for its use in coating the cylinder bores of an engine, enabling the use of aluminum engine blocks without the need for heavy cast iron sleeves.

Plasma cutting - Wikipedia

Plasma cutting grew out of plasma welding in the 1960s, and emerged as a very productive way to cut sheet metal and plate in the 1980s. It had the advantages over traditional "metal against metal" cutting of producing no metal chips, giving accurate cuts, and producing a cleaner edge than oxy-fuel cutting.Early plasma cutters were large, somewhat slow and expensive and, therefore, tended to be ...

Plasma cutting - Wikipedia

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma.Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and ...
