New trends of thermal spray technique in materials recycling and integration

摘要

Thermal Spray was invented by Swiss scientist Max Ulrih Schoop in 1919s and became and industrial coating technology used to modify the surface of materials to make them more wear, corrosion or thermally resistant, or to let them have functional properties such as photocatalytic activity.In this lecture, new trends of thermal spray technique in materials recycling and integration are presented.The development status of thermal spray in Joining and Welding Research Institute at Osaka University are also given. The emphases will be made on the smart processing technique, the utilization of plastic materials, and also the special phenomena taking place in it such as implantation of particle to plastic substrate.Furthermore, the smart coating processes relating to the velocity, temperature and the reactive processes in composite powder or powder with plasma or flame are discussed in details. Moreover, the International Thermal Spray Conference & Exhibition open at Osake on May 2004 are introduced and the experience and success are shared.
