利用粉末冶金技術(shù)燒結(jié)齒輪的時候，淮安不銹鋼粉末冶金，先要計算齒輪模腔的齒型的型廓，然后再結(jié)合齒輪的齒根過渡曲線來對產(chǎn)品進行修正，以得到佳的圓角。在這過程中，還要考慮粉末冶金齒輪的有限元齒根彎曲強度和佳齒形變位等等，以確保齒輪產(chǎn)品，淮安不銹鋼粉末冶金。上面提高的燒結(jié)齒輪的模腔的齒型型廓計算一般是利用齒廓法線法得到了，這樣就可以直接利用齒廓嚙合基本定律，把接觸點在給定點的位置和齒輪轉(zhuǎn)角間建立起關(guān)系，淮安不銹鋼粉末冶金。這樣我們就可以一目了然了，加工的時候也更加方便了。

碳分解出后被金屬表面吸收并逐漸向內(nèi)部擴散，在材料的表面獲得足夠的碳濃度后再進行淬火和回火處理，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，完成化學熱處理的過程。但是，材料密度越高，孔隙效應就越弱，化學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。根據(jù)粉末冶金材料的孔隙特點，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熱處理包括滲碳、滲氮、滲硫和多元共滲等幾種形式，在化學熱處理中，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措施，比如：滲碳時，在材料密度大于7g/cm3時適當延長時間。通過化學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。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="淮安不銹鋼粉末冶金" src="https://tyunfile.71360.com/UploadFile/lmfmyj/637249885633291016/5569944.jpg"></div><p> 由于粉末冶金工藝在材料生產(chǎn)過程中并不熔化材料，也就不怕混入由坩堝和脫氧劑等帶來的雜質(zhì)，而燒結(jié)一般在真空和還原氣氛中進行，不怕氧化，也不會給材料任何污染，故有可能制取高純度的材料。 </p> <p> 很多新興金屬材料的制作研發(fā)與粉末冶金密切相關(guān)。粉末冶金是以金屬粉末為原料，經(jīng)過成型和固結(jié)，制造金屬材料、復合材料及制品的工藝過程。高性能金屬粉末的開發(fā)與生產(chǎn)，對提高粉末冶金材料和制品性能、推動粉末冶金技術(shù)進步起著至關(guān)重要的作用。 </p><div
