不锈钢焊管模具表面超硬化处理技术一、扩散法金属碳化物覆层技术介绍 1、 技术简介扩散法金属碳化物覆层技术是将工件置于特种介质中,经扩散作用于工件表面形成一层数微米至数十微米的金属碳化物层。该碳化物层具有极高的硬度,HV可达1600~3000(由碳化物种类决定),此外,该碳化物履层与基体冶金结合,不影响工件表面光洁度,具有极高的耐磨、抗咬合(粘结)、耐蚀等性能,可大幅度提高工模具及机械零件的使用寿命。2、 与相关技术的比较通过在工件表面形成超硬化合物膜层的方法,是大幅度提高其耐磨、抗咬合(抗粘结)、耐蚀等性能,从而大幅度提高其使用寿命的有效而经济的方法。目前,工件表面超硬化处理方法主要有物理气相沉积(PVD),化学气相沉积(CVD),物理化学气相沉积(PCVD),扩散法金属碳化物履层技术,其中,PVD法具有沉积温度低,工件变形小的优点,但由于膜层与基体的结合力较差,工艺绕镀性不好,往往难以发挥超硬化合物膜层的性能优势。CVD法具有膜基结合力好,工艺绕镀性好等突出优点,但对于大量的钢铁材料而言,其后续基体硬化处理比较麻烦,稍有不慎,膜层就易破坏。因此其应用主要集中在硬质合金等材料上。PCVD法沉积温度低,膜基结合力及工艺绕镀性均较PVD法有较大改进,但与扩散法相比,膜基结合力仍有较大差距,此外由于PCVD法仍为等离子体成膜,虽然绕镀性较PVD法有所改善,但无法消除。由扩散法金属碳化物覆层技术形成的金属碳化物覆层,与基体形成冶金结合,具有PVD、PCVD无法比拟的膜基结合力,因此该技术真正能够发挥超硬膜层的性能优势,此外,该技术不存在绕镀性问题,后续基体硬化处理方便,并可多次重复处理,使该技术的适用性更为广泛。3、 技术优势扩散法金属碳化物覆层技术在日本、欧洲各国、澳大利亚、韩国等国应用广泛。据调查,许多进口设备上的配套模具大量地使用了该技术,这些模具在进行国产化时,由于缺乏相应的成熟技术,往往使模具寿命低,有些甚至无法国产化。
