style="text-indent:25px">硬質(zhì)合金涂層在切削加工中，刀具性能對切削加工的效率、精度、表面質(zhì)量有著決定性的影響。硬質(zhì)合金刀具性能的兩個關(guān)鍵指標—硬度和強度之間總存著矛盾，硬度高的材料強度低，江西金屬表面耐熱涂層哪家好，而提**度往往是以硬度的降低為代價。為了解決硬質(zhì)合金材料中存在的這種矛盾，更好地提高刀具的切削性能，江西金屬表面耐熱涂層哪家好，比較有效的一種方法是采用各種涂層技術(shù)在硬質(zhì)合金基體上涂覆上一層或多層高硬度、高耐磨損性能的材料。硬質(zhì)合金刀具表面上的涂層作為一個化學屏障和熱屏障，減少了硬質(zhì)合金刀具的月牙洼磨損，可以***地提高加工效率，江西金屬表面耐熱涂層哪家好、提高加工精度、延長刀具使用壽命、降低加工成本。常州卡奇液壓機械有限公司是噴涂硬質(zhì)合金加工供應商！江西金屬表面耐熱涂層哪家好</p><div

style="text-indent:25px">二十世紀六十年代以來，CVD技術(shù)被應用于硬質(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合涂層的沉積，涂層與基體結(jié)合強度較高，薄膜厚度可達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)部呈拉應力狀態(tài)，易導致刀具使用時產(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)展和應用受到一定制約。</p><p
