Abstract:

Mechanical ball milling technique has attracted wide attention because of its simpler process and lower cost,it has a wide application prospect in the fields of mixing,refinement and alloying of powder materials.The present status of application of mechanical coating technique(MCT)developed from the principle of mechanical ball milling were summarized,including preparation of the functional coatings for surface modification of material and the thin films for photocatalytic degradation.The effects of process parameters,coating materials and coating substrate on the coatings′ thickness were analyzed. The unique advantages,such as simpler process,lower cost and formation of films on the spherical and other complex substrates,of this technique in the preparation of thin films were discussed.Based on the current research situation that uncontrollable films′ morphology,thickness and limited films′ substrate obtained from MCT,the future development direction of this technique was prospected aimed at expanding the types of films-forming substrate materials and accelerating the practical application of the thin films materials prepared by MCT.

Key words: mechanical coating technique, surface modification, coatings, photocatalysis, films
