每一種物質(zhì)都有自身的硬度，而硬度的書面意思為材料抵抗其他物體體壓入其表面的一種能力。我們模具中的所有指標(biāo)基本都需要使用到材料的各種物理特性，而硬度是**重要的方面。從材料的物理特性來說，一般是越硬就是越耐磨，伴隨的也是越脆。但是，目前世界上用來表示物體硬度的單位（表示方法）有好幾種。模具材料中，大部分硬度的表示方法為洛氏硬度，除此以外還有：布氏硬度、維氏硬度等。到底這些硬度有哪些不同？又是怎么的出來的呢？洛氏硬度(單位：HR)得到洛氏硬度的方法：用一個(gè)頂角120°的金剛石圓錐體或直徑為、，通過給金剛石、或者鋼球加固定的一個(gè)壓力，將其壓入被檢測材料的表面，再通過觀察、測量出被測材料表面的凹陷程度來得出硬度值。如檢測HRC：就是通過150kg載荷、鉆石錐以上述方法得到硬度，不過此方法多用于硬度很高的材料(如淬火鋼等)。布氏硬度(單位：HB)得到布氏硬度的方法：通過給一個(gè)鋼球施加一個(gè)大約3000kg的力，讓后將其壓入材料，而且需要保持一段時(shí)間后，去除外力。然后通過檢查其表面的凹痕，得到布氏硬度值。其單位為公斤力/mm2(N/mm2)。維氏硬度(單位：HV)得到維氏硬度的方法：通過將頂角為136°的金剛石方形錐施加一個(gè)大約120kg力?？诒糜捕葯C(jī)使用方法里氏硬度計(jì)主要功能：可通過按鍵選擇測試材料、硬度制式、測試方向及測試次數(shù)。</p><div
