Applications on Nanocomposite Coating Technology in Plastic Injection Mould Cavity Surface Treatment

摘要

Nano surface engineering is a protection technology using nanometer material and nanometer technology, pointing at failure forms, characteristics and mechanism, comprehensively using a variety of traditional surface engineering technology. Nanocomposite coating technology which develops on the basis of the traditional composite coating technology was briefly introduced in the article. The research of application nanocomposite coating technology in plastic injection mould cavity surface treatment has just started. The nanocomposite coating technology was compared with the ordinary nickel electro-brush coating and the basic approach which realizes nanometer on the mould cavity was described. The advantages of nanocomposite coating were comprehensively and effectively explained. It can increase the coating thickness and hardness, improve the abrasive resistance, fatigue resistance and corrosion resistance of the plastic injection mould cavity, thereby enhancing the service life of mould.
