Webusing a plasma-transfer wire-arc (PTWA) process and a high-velocity oxy-fuel (HVOF) process were studied. The coatings investigated consisted of PTWA 1020, HVOF 1020 deposited from a low-carbon steel wire stock, and HVOF 1020-2.5 pct Al produced using a wire stock with 2.5 wt pct Al added to the base AISI 1020 composition. WebPlasma Transferred Wire Arc(PTWA) differs from traditional plasma arc welding techniques which are known as Wire Arc Spray Welding (WASW). PTWA relies on just the one wire for …
WebThe powdered or wire material is generally known as a flame spray powder and is usually of a relatively small particle size, as, for example, below about 140 mesh U.S. Standard screen size. The flame spray guns utilize a combustion or plasma flame and in many guns the powder or wire is fed to the gun or into the gun's flame entrained in a ...
