600x的放大倍數(shù)是**常見(jiàn)的。6布氏硬度（HB）以1-3000kgf的試驗(yàn)力，將直徑分別為1,,5或10mm的硬質(zhì)合金球或碳化鋼球壓入被測(cè)材料表面。相對(duì)大的壓痕則應(yīng)用顯微鏡或USB攝像頭來(lái)進(jìn)行視頻觀測(cè)及測(cè)量。7里氏硬度（HL）（回彈方式）便攜式硬度測(cè)試。它是用一定質(zhì)量的裝有碳化鎢球頭的沖擊體，在一定彈簧彈力的作用下沖擊試件表面，這種沖擊力使被測(cè)材料表面產(chǎn)生了塑性變形，形成了一個(gè)壓痕,隨之沖擊體失去了原有的速度（或能量）。因此，被測(cè)材料越柔軟，沖擊體在回彈過(guò)程中失去的速度就越多。里氏硬度可以應(yīng)用于多種零件，需要遵守的測(cè)試要求也很少。8超聲波硬度測(cè)試（UCI）便攜式硬度測(cè)試。一個(gè)維氏形狀的金剛石壓頭固定在一個(gè)震蕩棒上，以一定的力值加于被測(cè)材料表面，然后根據(jù)超音波振動(dòng)，分析它的阻尼效應(yīng)，從而測(cè)量材料的硬度值。超聲波硬度測(cè)試多用于較小，較薄而無(wú)法用回彈硬度試驗(yàn)儀所測(cè)試的零件。9邵氏硬度（SHORE）便攜式（橡膠/塑料制品）硬度測(cè)試。邵氏硬度是用具有一定形狀的鋼制壓針，在試驗(yàn)力作用下垂直壓入試樣表面﹐當(dāng)壓足表面與試樣表面完全貼合時(shí)﹐壓針前列面相對(duì)壓足平面有一定的伸出長(zhǎng)度(即壓針扎進(jìn)被測(cè)物的深度)，以該長(zhǎng)度值的大小來(lái)表示邵氏硬度的大小。手動(dòng)硬度機(jī)訂制價(jià)格HRA：是采用60kg載荷和鉆石錐壓入器求得的硬度，用于硬度極高的材料（如硬質(zhì)合金等）。</p><div

里氏硬度計(jì)為成品、半成品模具的硬度測(cè)試提供了一個(gè)解決方案，可以先測(cè)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(cè)量是目前模具行業(yè)應(yīng)用**為普遍的硬度測(cè)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(méi)有更好的解決辦法。對(duì)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(cè)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(cè)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(cè)試更準(zhǔn)確。測(cè)得的HRA硬度值可方便地通過(guò)查表?yè)Q算成HRC硬度值。對(duì)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(cè)試成品模具。待***點(diǎn)測(cè)試完，硬度計(jì)處于正常運(yùn)行機(jī)制狀態(tài)后再對(duì)試樣進(jìn)行正式測(cè)試，記錄測(cè)得的硬度值。</p><div

表3-1維氏硬度試驗(yàn)的三種方法維氏硬度試驗(yàn)可選用的試驗(yàn)力值很多，見(jiàn)表3-2。表3-2推薦的維氏硬度試驗(yàn)力試驗(yàn)力的選擇要根據(jù)試樣種類、試樣厚度和預(yù)期的硬度范圍而定。標(biāo)準(zhǔn)規(guī)定，試樣或試驗(yàn)層的厚度至少為壓痕對(duì)角線長(zhǎng)度的。試驗(yàn)后試樣背面不應(yīng)出現(xiàn)可見(jiàn)的變形痕跡。維氏硬度試驗(yàn)的優(yōu)點(diǎn)維氏硬度試驗(yàn)的壓痕是正方形，輕廓清晰，對(duì)角線測(cè)量準(zhǔn)確，因此，維氏硬度試驗(yàn)是常用硬度試驗(yàn)方法中精度高的，同時(shí)它的重復(fù)性也很好，這一點(diǎn)比布氏硬度計(jì)優(yōu)越。維氏硬度試驗(yàn)測(cè)量范圍寬廣，可以測(cè)量目前工業(yè)上所用到的幾乎全部金屬材料，從很軟的材料（幾個(gè)維氏硬度單位）到很硬的材料（3000個(gè)維氏硬度單位）都可測(cè)量。維氏硬度試驗(yàn)大的優(yōu)點(diǎn)在于其硬度值與試驗(yàn)力的大小無(wú)關(guān)，只要是硬度均勻的材料，可以任意選擇試驗(yàn)力，其硬度值不變。這就相當(dāng)于在一個(gè)很寬廣的硬度范圍內(nèi)具有一個(gè)統(tǒng)一的標(biāo)尺。這一點(diǎn)又比洛氏硬度試驗(yàn)來(lái)得優(yōu)越。在中、低硬度值范圍內(nèi)，在同一均勻材料上，維氏硬度試驗(yàn)和布氏硬度試驗(yàn)結(jié)果會(huì)得到近似的硬度值。例如，當(dāng)硬度值為400以下時(shí)，HV≈HB，如圖3-2所示。維氏硬度試驗(yàn)的試驗(yàn)力可以小到10gF，壓痕非常小，特別適合測(cè)試薄小材料。維氏硬度試驗(yàn)的缺點(diǎn)維氏硬度試驗(yàn)效率低。ATM硬度機(jī)批量定制</p><p>
