components share and layout changes. Therefore, the skills relative to the coating (layer) skills and welding surface modification skills are skills simple, only need to control process parameters. Need not the same conditions of information is not the same, should be based on the detailed practical need to select management skills.

化学转化膜技能，该技能通过近些年的开展现已完成了不仅在金属资料外表成膜，并且可在陶瓷等非金属外表成膜，膜的厚度也在向着更优更薄的方向开展。如各种碳化钛超导陶瓷薄膜系多晶或外延单晶薄膜、抗高温大功率的半导体用金刚石薄膜以及各种光电子薄膜和集成光学薄膜。铝及其合金的外表改性技能大多选用的是外表成膜技能，在外表构成耐磨、耐蚀、多孔、太阳能热水工程联系性强的高功能薄膜。当前铝合金外表的改性技能主要有：电化学氧化法、化学转化法、微弧氧化技能、等离子写入外表改性、冷喷涂技能、稀土转化膜和激光处置等。高能束外表改性技能，锅炉辅机高能束外表改性技能是运用高能束热源，增加或不加化学元素，对资料外表及亚外表进行重熔或熔覆处置。

Chemical conversion film skill, the skill through in recent years development has been done not only in the metal material surface film, and film on ceramic non-metallic surface, the thickness of the film is also carried out in more and more thin direction. Such as all kinds of titanium carbide ceramic
