每一種物質(zhì)都有自身的硬度，而硬度的書面意思為材料抵抗其他物體體壓入其表面的一種能力。我們模具中的所有指標(biāo)基本都需要使用到材料的各種物理特性，而硬度是**重要的方面。從材料的物理特性來說，一般是越硬就是越耐磨，伴隨的也是越脆。但是，目前世界上用來表示物體硬度的單位（表示方法）有好幾種。模具材料中，大部分硬度的表示方法為洛氏硬度，除此以外還有：布氏硬度、維氏硬度等。到底這些硬度有哪些不同？又是怎么的出來的呢？洛氏硬度(單位：HR)得到洛氏硬度的方法：用一個(gè)頂角120°的金剛石圓錐體或直徑為、，通過給金剛石、或者鋼球加固定的一個(gè)壓力，將其壓入被檢測材料的表面，再通過觀察、測量出被測材料表面的凹陷程度來得出硬度值。如檢測HRC：就是通過150kg載荷、鉆石錐以上述方法得到硬度，不過此方法多用于硬度很高的材料(如淬火鋼等)。布氏硬度(單位：HB)得到布氏硬度的方法：通過給一個(gè)鋼球施加一個(gè)大約3000kg的力，讓后將其壓入材料，而且需要保持一段時(shí)間后，去除外力。然后通過檢查其表面的凹痕，得到布氏硬度值。其單位為公斤力/mm2(N/mm2)。維氏硬度(單位：HV)得到維氏硬度的方法：通過將頂角為136°的金剛石方形錐施加一個(gè)大約120kg力。各硬度值相互之間不能直接比較，只能通過硬度對照表換算。</p><div

里氏硬度計(jì)為成品、半成品模具的硬度測試提供了一個(gè)解決方案，可以先測試模具的里氏硬度，然后再換算成HRC洛氏硬度。里氏硬度計(jì)測量是目前模具行業(yè)應(yīng)用**為普遍的硬度測試方法，而且時(shí)代里氏硬度計(jì)應(yīng)用*****的領(lǐng)域就是模具行業(yè)。如前面所述，成品、半成品模具合理的硬度范圍是比較窄的，里氏硬度計(jì)不能滿足這樣的精度要求。但是這就是目前模具行業(yè)的現(xiàn)狀，沒有更好的解決辦法。對于進(jìn)行了表面的滲碳、滲氮或激光淬火處理，表面硬化處理的模具需要測試模具的表面硬度。滲碳層通常較厚，當(dāng)滲碳層厚度大于，可直接用洛氏硬度計(jì)，測試HRC硬度。當(dāng)滲碳層厚度在，可以采用洛氏硬度計(jì)的A標(biāo)尺。A標(biāo)尺的試驗(yàn)力較小，只有60kg（C標(biāo)尺試驗(yàn)力是150kg），可以在模具表面壓一個(gè)較淺的壓痕，不至于將硬化層壓透，硬度測試更準(zhǔn)確。測得的HRA硬度值可方便地通過查表換算成HRC硬度值。對于較薄的滲碳層或滲氮層，只要厚度大于，都可以采用表面洛氏硬度計(jì)。表面洛氏硬度計(jì)的試驗(yàn)力只有15kg、30kg或45kg。表面洛氏硬度壓痕更小，例如，模具硬度為60HRC時(shí)，表面洛氏硬度值為，壓痕深度等于（），這樣的壓痕肉眼幾乎難于分辨。因此表面洛氏硬度計(jì)還可以測試成品模具。陜西金屬硬度機(jī)供應(yīng)商</p><p
