降低回火脆性的影響，一般的材料可在175-250℃下空氣或油中回火。2、化學(xué)熱處理工藝化學(xué)熱處理一般都包括分解、吸收、擴(kuò)散三個(gè)基本過(guò)程，比如，滲碳熱處理的反應(yīng)如下：2CO≒[C]+CO2(放熱反應(yīng))CH4≒[C]+2H2(吸熱反應(yīng))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(huì)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(guò)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(shì)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(shí)要延長(zhǎng)保溫時(shí)間，提高加熱溫度。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(shí)，在材料密度大于7g/cm3時(shí)適當(dāng)延長(zhǎng)時(shí)間。通過(guò)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。虹口區(qū)直銷金屬注射成型服務(wù)商</p><p
