600x的放大倍數(shù)是**常見的。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，端淬硬度機(jī)。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，端淬硬度機(jī)，形成了一個(gè)壓痕，端淬硬度機(jī),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度(即壓針扎進(jìn)被測(cè)物的深度)，以該長度值的大小來表示邵氏硬度的大小。觸屏技術(shù)可更簡單、更經(jīng)濟(jì)地實(shí)現(xiàn)檢驗(yàn)過程的記錄、顯示、控制和數(shù)據(jù)的存儲(chǔ)。端淬硬度機(jī)</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)角線長度的。試驗(yàn)后試樣背面不應(yīng)出現(xiàn)可見的變形痕跡。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。端淬硬度機(jī)其他硬度測(cè)試法也都規(guī)定有相應(yīng)的校正標(biāo)準(zhǔn)。</p><div

硬度，**常用的指標(biāo)有三種：布氏硬度，洛氏硬度和維氏硬度。布氏硬度的含意：用一定直徑的淬硬鋼球，在一定的載荷（p）作用下，壓入試件表面，停留一段時(shí)間，然后除去載荷，測(cè)量壓痕的面積，壓痕越小表示抵抗塑性變形能力（即硬度）越大，越大硬度越小，用“HB”來表示。維氏硬度的含意：在規(guī)定的外加載荷下，將鋼球或金剛石壓頭垂直壓入試件表面，產(chǎn)生壓痕，測(cè)試壓痕深度，利用洛氏硬度計(jì)算公式HR=（K-H)/C便可計(jì)算出洛氏硬度。簡單說就是壓痕越淺，HR值越大，材料硬度越高。用"HRC"來表示。比如HRC60，即**在試驗(yàn)載荷為150kg下，使用頂角為120度的金剛石圓錐壓頭時(shí)，試件的壓痕深度為。布氏硬度的含意：是利用頂角為136度的金剛石四方角錐體作壓頭，在一定的載荷下壓入試件表面，留下方形壓痕，根據(jù)對(duì)角線的長度，即可查出硬度值，用“HV”來表示。一般都是用洛氏硬度來衡量刀刃的硬度，也就是HRC值，通常一把好刀的刀刃硬度應(yīng)在洛氏威爾硬度50s以上，60s以下，簡而言之，硬度越高，抗磨損能力越高，但脆性也越大。國外dao具用鋼全集美國**刀常用不銹鋼性能差不多是BG42（克瑞斯用得**多）約等于VG10>154CM（蝴蝶，微技術(shù)，MOG用得**多）>ATS34。硬度和裝配、精加工工序一樣是決定零件質(zhì)量的重要因素。布式硬度機(jī)便宜</p><p
