Abstract
For the purpose of eliminating the sleeve from the cylinder, we chose to rely on plasma spraying technology because of its high applicability to die-cast cylinders. This study led to a successful development of low cost, plasma spray coated cylinders. The performance of the plasma spray coated cylinders was verified by analyzing the developed coating and by a dynamometer endurance test. The applicability of the plasma spray coating to die-cast materials was also confirmed to verify the potential of sleeveless die-cast cylinders by plasma spraying.
