style="text-indent:25px">涂層（coating）是涂料一次施涂所得到的固態(tài)連續(xù)膜，是為了防護(hù)，絕緣，裝飾等目的，涂布于金屬，織物，塑料等基體上的塑料薄層。涂料可以為氣態(tài)、液態(tài)、固態(tài)，通常根據(jù)需要噴涂的基質(zhì)決定涂料的種類和狀態(tài)。高溫電絕緣涂層用銅、鋁等金屬做成的導(dǎo)線外面，或有絕緣漆、或有塑料、橡膠等絕緣包皮。然而，絕緣漆、塑料、橡膠都怕高溫，一般超過200℃就會集化，失去絕緣性能。而許多電線正需要在高溫下工作，那該怎么辦呢?對，讓高溫電絕緣涂層來幫忙，這種涂層實際上是一種陶瓷涂層，它除了能在高溫下保持電絕緣性能外，還能與金屬導(dǎo)線緊密“團結(jié)”在一起，做到“天衣無縫”，任你將導(dǎo)線七繞八彎，它們也不會分離，這種涂層非常致密，涂上它，兩根電壓差很大的導(dǎo)線碰在一起，也不會發(fā)生擊穿現(xiàn)象。</p><p style="text-indent:25px">二十世紀(jì)六十年代以來，CVD技術(shù)被廣泛應(yīng)用于硬質(zhì)合金可轉(zhuǎn)位刀具的表面處理。由于CVD工藝氣相沉積所需金屬源的制備相對容易，可實現(xiàn)TiN、TiC、TiCN、TiBN、TiB2、Al2O3等單層及多元多層復(fù)合涂層的沉積，涂層與基體結(jié)合強度較高，薄膜厚度可達(dá)7～9μm，因此到八十年代中后期，美國已有85%的硬質(zhì)合金工具采用了表面涂層處理，其中CVD涂層占到99%；到九十年代中期，CVD涂層硬質(zhì)合金刀片在涂層硬質(zhì)合金刀具中仍占80%以上。盡管CVD涂層具有很好的耐磨性，但CVD工藝亦有其先天缺陷：一是工藝處理溫度高，易造成刀具材料抗彎強度下降；二是薄膜內(nèi)部呈拉應(yīng)力狀態(tài)，易導(dǎo)致刀具使用時產(chǎn)生微裂紋；三是CVD工藝排放的廢氣、廢液會造成較大環(huán)境污染，與目前大力提倡的綠色制造觀念相抵觸，因此自九十年代中期以來，高溫CVD技術(shù)的發(fā)展和應(yīng)用受到一定制約。硬質(zhì)合金刀具表面上的涂層作為一個化學(xué)屏障和熱屏障！</p><div

style="text-indent:25px">涂層的特點是涂層薄膜與刀具基體相結(jié)合，提高刀具的耐磨性而不降低基體的韌性，從而降低刀具與工件的摩擦因素，延長刀具的使用壽命。此外，由于涂層自身的熱傳導(dǎo)系數(shù)比刀具基體和加工材料低的多，能有效減少摩擦所產(chǎn)生的熱量，形成熱屏障，改變熱量的散失途徑，從而降低刀具與工件、刀具與切削之間的熱沖擊和力沖擊，有效地改善刀具的使用性能。刀具磨損機理研究表明，在高速切削時，刀刃溫度比較高可達(dá)900℃，此時刀具磨損不*是機械摩擦磨損(刀具后面磨損)，還有粘結(jié)磨損、擴散磨損、摩擦氧化磨損(刀具刀刃磨損及月牙洼磨損)和疲勞磨損，到400℃仍有良好的電絕緣性能！無錫合金涂層工藝</p><p
