PTWA process as an economically viablealternative to the conventional regenerationmethod for cylinder crankcases
Dipl. Ing. Leander Schramm
The regeneration of cylinder crankcases subjected to operating stresses makes a
contribution to reducing CO2 and to saving valuable raw materials and resources.
Nevertheless, conventional repair processes reach their technical and economic
limits in the case of modern engines. The thermal coating industry offers the
possibility of restoring cylinder liner surfaces in a cost-favourable way, while simultaneously
dispensing with oversize pistons and without weakening the
structure of the cylinder crankcase. As a wire-based spraying process, the PTWA
(Plasma Transferred Wire Arc) system developed by Ford is a cost-favourable alternative
to existing rotating lining processes and is optimally suitable as a new
restoration process for cylinder liner surfaces.
