碳分解出后被金屬表面吸收并逐漸向內(nèi)部擴(kuò)散，在材料的表面獲得足夠的碳濃度后再進(jìn)行淬火和回火處理，會提高粉末冶金材料的表面硬度和淬硬深度。由于粉末冶金材料的孔隙存在，使得活性炭原子從表面滲入內(nèi)部，完成化學(xué)熱處理的過程。但是，材料密度越高，孔隙效應(yīng)就越弱，化學(xué)熱處理的效果就越不明顯，因此，要采用碳勢較高的還原性氣氛保護(hù)。根據(jù)粉末冶金材料的孔隙特點(diǎn)，其加熱和冷卻速度要低于致密材料，所以加熱時要延長保溫時間，提高加熱溫度。 </p> <p> 粉末冶金材料的化學(xué)熱處理包括滲碳、滲氮、滲硫和多元共滲等幾種形式，在化學(xué)熱處理中，淬硬深度主要與材料的密度有關(guān)。因此，可以在熱處理工藝上采取相應(yīng)措施，比如：滲碳時，在材料密度大于7g/cm3時適當(dāng)延長時間。通過化學(xué)熱處理可提高材料的耐磨性，粉末冶金材料的不均勻奧氏體滲碳工藝，使處理后的材料滲層表面的含碳量可達(dá)2%以上，碳化物均勻分布于滲層表面，能夠很好地提高硬度和耐磨性能。
