步驟1—在垂直于表面的方向使規(guī)定的合適壓頭壓到試樣上面并施加試驗力F。將試驗力保持一定時間后卸除。 5.1.2 步驟2—對于維氏硬度試驗，測量兩條對角線的長度并計算平均對角線長度(其可被用于推導(dǎo)維氏硬度值)。對于努氏硬度試驗，測量長對角線的長度(其可被用于推導(dǎo)努氏硬度值)。 5.1.3 當(dāng)在加載循環(huán)結(jié)束后移走壓頭時，大多數(shù)材料都將展現(xiàn)出一些彈性恢復(fù)。但如果要利用壓痕的對角線長度計算硬度值，則應(yīng)假設(shè)壓痕仍保持卸除試驗力之后的壓頭形狀。在努氏試驗中，則應(yīng)假設(shè)壓痕的長對角線與短對角線之比壓頭的相同。 5.2 試驗機—試驗機應(yīng)能支撐試樣并控制壓頭以預(yù)先設(shè)定的試驗力壓入試樣，并且應(yīng)配備有一個光學(xué)顯微鏡，以選擇期望的試驗位置并測量試驗中所產(chǎn)生的壓痕尺寸。試樣表面的平面宜垂直于壓頭的軸線(即施加力的方向)。 5.2.1 試驗機的特征、限制和各種操作程序的描述見設(shè)備制造商的使用手冊。定制硬度測試儀對照表維氏硬度計：主要是用于測黑色金屬、有色金屬、硬質(zhì)合金（如鋁合金）及表面滲碳、滲氮層的硬度，用HV表示。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

GB/T231.1-2018的圖C.1示出了硬度標(biāo)尺的定義和量值傳遞所需的計量鏈。測量不確定度分析是一個有用的工具，有助于確定誤差源并了解測量值之間的差異。本附錄給出了不確定度評定指南，評定示例中推導(dǎo)出的值*供參考，但客戶特別指定的除外。本部分中對硬度計的性能規(guī)定的指標(biāo)，是經(jīng)過相當(dāng)長的一段時間才研發(fā)完善起來的。當(dāng)在確定硬度計需要滿足的一個具體的允差時,與所使用的計量器具和/或參考標(biāo)準(zhǔn)相關(guān)的不確定度就已經(jīng)包含在該允差之內(nèi)了，因此對該不確定度的限值欲做進(jìn)一步的任何修正（例如，減小測量不確定度的允差）都是不適當(dāng)?shù)摹＿@適用于在對硬度計進(jìn)行直接或間接檢驗過程中做的所有測量。在不同情況下，使用規(guī)定的計量器具和/或參考標(biāo)準(zhǔn)測得的簡化測量值可用于評估硬度計是否符合本部分。然而，也可能有適合減小測量不確定度允差的特殊情況，但這只能在所有相關(guān)方共同協(xié)商一致后方可進(jìn)行操作。采用便攜式里氏硬度計進(jìn)行硬度檢測的實用價值在于不必破壞工件并可成批檢驗零件。多壓頭硬度測試儀哪里定制</p><p style="text-indent:25px">布氏硬度的鋼球壓頭直徑增加，其硬度值減硬度檢測儀硬度檢測儀小。重型硬度測試儀批量定制</p><p style="text-indent:25px">6.2 金剛石壓頭 6.2.1 總則為檢驗金剛石壓頭的可靠性，應(yīng)按本部分的要求對每個壓頭進(jìn)行直接和間接的校準(zhǔn)與檢驗。 6.2.2 金剛石壓頭的直接校準(zhǔn)與檢驗 6.2.2.1 與0.3 mm壓入深度范圍相對應(yīng)的金剛石圓錐面和頂端球面應(yīng)拋光，兩個面的結(jié)合應(yīng)光滑相切。兩個面應(yīng)無表面缺痕。 6.2.2.2 壓頭的形狀可通過直接測量或光學(xué)測量進(jìn)行檢驗。檢驗應(yīng)在至少4個等間隔的不同軸截面上進(jìn)行（例如0°、45°、90°、135°）。也可以使用準(zhǔn)直儀進(jìn)行測量，在這種情況下，宜在至少4個中心角上進(jìn)行測量，且應(yīng)包括120°的中心角。金剛石壓頭頂端球面與圓錐結(jié)合的位置會因頂端球面半徑和圓錐角度的不同而改變。理論上一個完美壓頭的幾何形狀的結(jié)合點，沿壓頭軸線的一條垂線測量，應(yīng)位于距壓頭軸線100 μm的位置。為避免在頂端球面半徑和圓錐角度測量中包含二者的結(jié)合區(qū)域，可忽略金剛石表面80 μm到120 μm之間的部分。重型硬度測試儀批量定制</p><p>
