Development of coating and cladding technology, MSCoating, using electro-discharge energy

Abstract

IHI and Mitsubishi Electric Corporation have developed revolutionary coating and cladding technology, named Micro Spark Coating (MSCoating), which can stably build up functional coating and cladding, and is expected to replace for plating, welding and plasma spraying. Fundamental tests for application to aero-engines were carried out. MSCoating showed better performance than existing methods. Superior anti-fretting coating over a wide temperature range was developed for low-pressure turbine blades. Many simulated samples of actual parts were processed to promote engineering managers to adopt this technology, by showing the possibility of big cost reduction.
