這一點(diǎn)對(duì)于金屬加工和機(jī)械制造工廠具有重要意義。當(dāng)表面熱處理硬化層較厚時(shí)，也可采用洛氏硬度計(jì)。當(dāng)熱處理硬化層厚度在～，可采用HRA標(biāo)尺，當(dāng)硬化層厚度超過，可采用HRC標(biāo)尺。維氏、洛氏和表面洛氏三種硬度值可以方便地進(jìn)行相互換算，轉(zhuǎn)換成標(biāo)準(zhǔn)、圖紙或用戶需要的硬度值。相應(yīng)的換算表在國(guó)際標(biāo)準(zhǔn)ISO、美國(guó)標(biāo)準(zhǔn)ASTM和中國(guó)標(biāo)準(zhǔn)GB／T中都已給出。在沈陽(yáng)天星網(wǎng)站的技術(shù)資料欄目中這三種換算表都可以找到。2、化學(xué)熱處理化學(xué)熱處理是使工件表面滲入一種或幾種化學(xué)元素的原子，從而改變工件表面的化學(xué)成分、組織和性能。經(jīng)淬火和低溫回火后，工件表面具有高的硬度、耐磨性和接觸疲勞強(qiáng)度，而工件的芯部又具有高的強(qiáng)韌性?；瘜W(xué)熱處理工件的主要技術(shù)參數(shù)是硬化層深度和表面硬度。硬化層深度還是要用維氏硬度計(jì)來檢測(cè)。檢測(cè)從工件表面到硬度降到50HRC那一點(diǎn)的距離。這就是有效硬化深度。化學(xué)熱處理工件的表面硬度檢測(cè)與表面淬火熱處理工件的硬度檢測(cè)相近，都可以用維氏硬度計(jì)，多功能硬度機(jī)配件、表面洛氏硬度計(jì)或洛氏硬度計(jì)來檢測(cè)，只是滲氮厚的厚度較薄，一般不大于，這時(shí)就不能再采用洛氏硬度計(jì)了，多功能硬度機(jī)配件。3、局部熱處理零件如果局部硬度要求較高，可用感應(yīng)加熱等方式進(jìn)行局部淬火熱處理。硬度是金屬材料的重要性能指標(biāo)之一，多功能硬度機(jī)配件。一般硬度越高，耐磨性越好。多功能硬度機(jī)配件</p><div
