Through the use of surface modification technology, material surface can be changed into the one with different characteristics, for instance, from iron to titanium, aluminum to ceramic. This technology is widely used in various areas from key industries to frontier fields. TOCALO has the largest sales in the surface modification business at home and abroad.

Surface modification technology is classified into thermal spraying and other peripheral technologies. Thermal spraying is our core competence, which is a technology that produces highly functional coatings onto the surface of industrial equipments and other subjects. In this process, the metal, ceramics and other materials are melted, then, the molten materials are sprayed onto the subject. Additionally, as peripheral technologies, we are reinforcing four product lines, the TD process, the ZAC coating process ,PTA process, and PVD/DLC.
