摘要：

机械球磨技术因工艺简单、成本低廉而受到广泛关注,特别在粉体材料的混合、细化及合金化等领域有着广阔的应用前景。综述了由机械球磨原理发展而成机械涂覆技术的应用现状,包括用于材料表面改性的功能涂层和光催化降解的薄膜材料制备。分析了工艺参数、涂覆材料及涂覆基底等因素对涂覆效果（厚度）的影响规律,并对该技术在薄膜制备中表现出的简便、廉价且可在球形等形状复杂基底上成膜的独特优势做了讨论。基于当前机械涂覆技术制备的薄膜形貌、厚度不可控且成膜基底材质受限等现状,指出今后应该向拓展成膜基底材料类型和加快推进光催化薄膜材料的实际应用方向发展。

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.
