Micro-arc plasma oxidation (MAPO) is a well-established and reliable mass production technique after many years of development in TSMT. The MAPO, also known as plasma electrolytic oxidation, is an excellent candidate to replace the hard anodic coating, chromium plating, or thermal spray. The composition, chemical structure, microstructure and crystal structure can be modified according to the properties our customers need/require. Our team welcomes any challenge of new products or specifications. The basic procedures of MAPO mass production are as following：
