試驗(yàn)原理及試驗(yàn)裝置 5.1 維氏硬度和努氏硬度的試驗(yàn)原理—維氏壓痕硬度試驗(yàn)和努氏壓痕硬度試驗(yàn)的一般原理包括兩個(gè)步驟。 5.1，便攜式硬度測(cè)試儀品牌排行.1 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(yàn)力F。將試驗(yàn)力保持一定時(shí)間后卸除。 5.1.2 步驟2—對(duì)于維氏硬度試驗(yàn)，便攜式硬度測(cè)試儀品牌排行，測(cè)量?jī)蓷l對(duì)角線的長(zhǎng)度并計(jì)算平均對(duì)角線長(zhǎng)度(其可被用于推導(dǎo)維氏硬度值)。對(duì)于努氏硬度試驗(yàn)，便攜式硬度測(cè)試儀品牌排行，測(cè)量長(zhǎng)對(duì)角線的長(zhǎng)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(shí)，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(duì)角線長(zhǎng)度計(jì)算硬度值，則應(yīng)假設(shè)壓痕仍保持卸除試驗(yàn)力之后的壓頭形狀。在努氏試驗(yàn)中，則應(yīng)假設(shè)壓痕的長(zhǎng)對(duì)角線與短對(duì)角線之比壓頭的相同。 5.2 試驗(yàn)機(jī)—試驗(yàn)機(jī)應(yīng)能支撐試樣并控制壓頭以預(yù)先設(shè)定的試驗(yàn)力壓入試樣，并且應(yīng)配備有一個(gè)光學(xué)顯微鏡，以選擇期望的試驗(yàn)位置并測(cè)量試驗(yàn)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(yàn)機(jī)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(cè)。采用便攜式里氏硬度計(jì)進(jìn)行硬度檢測(cè)的實(shí)用價(jià)值在于不必破壞工件并可成批檢驗(yàn)零件。便攜式硬度測(cè)試儀品牌排行</p><div style="width:100%;text-align: center;"><img

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(jì)量鏈。測(cè)量不確定度分析是一個(gè)有用的工具，有助于確定誤差源并了解測(cè)量值之間的差異。本附錄給出了不確定度評(píng)定指南，評(píng)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(duì)硬度計(jì)的性能規(guī)定的指標(biāo)，是經(jīng)過(guò)相當(dāng)長(zhǎng)的一段時(shí)間才研發(fā)完善起來(lái)的。當(dāng)在確定硬度計(jì)需要滿足的一個(gè)具體的允差時(shí),與所使用的計(jì)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(duì)該不確定度的限值欲做進(jìn)一步的任何修正（例如，減小測(cè)量不確定度的允差）都是不適當(dāng)?shù)?。這適用于在對(duì)硬度計(jì)進(jìn)行直接或間接檢驗(yàn)過(guò)程中做的所有測(cè)量。在不同情況下，使用規(guī)定的計(jì)量器具和/或參考標(biāo)準(zhǔn)測(cè)得的簡(jiǎn)化測(cè)量值可用于評(píng)估硬度計(jì)是否符合本部分。然而，也可能有適合減小測(cè)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。
