PTWA (Plasma Transferred Wire Arc) is applied by electrically melting a steel wire inside a controlled plasma arc and spraying the molten material directly onto a prepared aluminum cylinder bore. The coating bonds mechanically and metallurgically to the substrate, forming a thin, extremely durable iron-based surface. After spraying, the bore is precision honed to final size and surface finish for proper ring sealing and oil control.
