硬度是一個專業(yè)的物理術(shù)語，材料局部抵抗硬物壓入其表面的能力稱為硬度。由于規(guī)定了不同的測試方法，所以有不同的硬度標(biāo)準(zhǔn)。各種硬度標(biāo)準(zhǔn)的力學(xué)含義不同，相互不能直接換算，但可通過試驗加以對比。彈簧鋼砍粗鐵小意思硬度一般分為三種：①劃痕硬度。主要用于比較不同礦物的軟硬程度，方法是選一根一端硬一端軟的棒，將被測材料沿棒劃過，根據(jù)出現(xiàn)劃痕的位置確定被測材料的軟硬。定性地說，硬物體劃出的劃痕長，軟物體劃出的劃痕短。②壓入硬度。主要用于金屬材料，方法是用一定的載荷將規(guī)定的壓頭壓入被測材料，以材料表面局部塑性變形的大小比較被測材料的軟硬。由于壓頭、載荷以及載荷持續(xù)時間的不同，壓入硬度有多種，主要是布氏硬度、洛氏硬度、維氏硬度和顯微硬度等幾種，全自動布氏硬度機技術(shù)參數(shù)。③回跳硬度。主要用于金屬材料，方法是使一特制的小錘從一定高度自由下落沖擊被測材料的試樣，并以試樣在沖擊過程中儲存（繼而釋放）應(yīng)變能的多少（通過小錘的回跳高度測定）確定材料的硬度。凌空削發(fā)不是神話在刀劍硬度的測試上，我們通常采用的是洛氏硬度測試中的HRC標(biāo)尺，通常用于測試淬火鋼、回火鋼、調(diào)質(zhì)鋼和部分不銹鋼。這是金屬加工行業(yè)應(yīng)用**多的硬度試驗方法，全自動布氏硬度機技術(shù)參數(shù)，全自動布氏硬度機技術(shù)參數(shù)。HRC適用范圍HRC20－67。為了能用硬度試驗代替某些機械性能試驗，生產(chǎn)上需要一個比較準(zhǔn)確的硬度和強度的換算關(guān)系。全自動布氏硬度機技術(shù)參數(shù)</p><div

某些塑料模具鋼還以預(yù)硬狀態(tài)（調(diào)質(zhì)處理）供貨，用戶可直接加工成模具而不必進行后續(xù)熱處理。模具鋼按鋼種分類可分為碳素工具鋼、合金工具鋼和高速工具鋼，中國標(biāo)準(zhǔn)對于各種模具鋼都規(guī)定了出廠硬度要求，要求對鋼材的退火硬度和試樣淬火硬度進行檢驗。時代里氏硬度計被***應(yīng)用，它測試快速，方便，測試值可自動轉(zhuǎn)換成布氏硬度值，因此得到一定程度的應(yīng)用。完成了機械加工的模具鋼材料要進行淬火回火處理，再經(jīng)過精磨和拋光就可成為成品模具。淬火回火處理后的模具硬度檢測更為重要，因為這時的材料硬度是一個非常重要的質(zhì)量指標(biāo)，它在很大程度上決定了成品模具的使用壽命。淬火回火的模具料要求使用洛氏硬度計，測試HRC洛氏硬度值。模具成品需要具有比較好的綜合力學(xué)性能，既要有足夠的硬度，同時還要有一定的韌性，而硬度和韌性是一對矛盾，為了在具有合理韌性的條件下，便模具具有較高的硬度，比較好的硬度值就會被限制在一個比較窄的范圍內(nèi)，通常只有2-4個HRC單位。成品、半成品模具的硬度測試是一個難于解決的問題。一直沒有一個較為理想的解決方案。只有少數(shù)體積和重量較小的模具可以搬到臺式洛氏硬度計上測試。全自動布氏硬度機技術(shù)參數(shù)洛氏硬度（HR）當(dāng)HB>450或者試樣過小時，不能采用布氏硬度試驗而改用洛氏硬度計量。</p><div

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：通過給一個鋼球施加一個大約3000kg的力，讓后將其壓入材料，而且需要保持一段時間后，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大約120kg力。全自動布氏硬度機技術(shù)參數(shù)</p><p>
