Plasma transfer wire arc ptwa coating
PTWA can be used to apply a coating to wear surfaces of engine or transmission components, serving as a plain bearing. For the cylinder bores of hypoeutectic aluminum-silicon alloy blocks, PTWA's main advantages over cast iron liners are reduced weight and cost. The thinner bore surface also allows for more compact bore spacing, and can potentially provide better heat transfer. WebFeb 2, 2024 · (LDS is also known as PTWA: Plasma Transfer Wire Arc.) Because the cylinders have a super coating of iron that is extremly resistant to wear is the reasoning.
