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(jiǎn)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(jiǎn)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。</p><p>
