2.肖式硬度(HS)=洛式硬度(HRC)+15

4.洛式硬度(HRC)=勃式硬度(BHN)/10-3

洛氏硬度HRC和布氏硬度HB等硬度對照區(qū)別和換算硬度

是衡量材料軟硬程度的一個性能指標(biāo)。硬度試驗的方法較多，原理也不相同，測得的硬度值和含義也不完全一樣。最普通的是靜負(fù)荷壓入法硬度試驗，即布氏硬度(HB)、洛氏硬度(HRA，HRB，HRC)、維氏硬度(HV)，橡膠塑料邵氏硬度(HA,HD)等硬度其值表示材料表面抵抗堅硬物體壓入的能力。最流行的里氏硬度（HL）、肖氏硬度(HS)則屬于回跳法硬度試驗，其值代表金屬彈性變形功的大小。因此，硬度不是一個單純的物理量，而是反映材料的彈性、塑性、強度和韌性等的一種綜合性能指標(biāo)。1、鋼材的硬度：金屬硬度(Hardness)的代號為H。按硬度試驗方法的不同，

●常規(guī)表示有布氏（HB）、洛氏（HRC）、維氏（HV）、里氏（HL）硬度等，其中以HB及HRC較為常用。

●HB應(yīng)用范圍較廣，HRC適用于表面高硬度材料，如熱處理硬度等。兩者區(qū)別在于硬度計之測頭不同，布氏硬度計之測頭為鋼球，而洛氏硬度計之測頭為金剛石。

●HV-適用于顯微鏡分析。維氏硬度(HV)以120kg以內(nèi)的載荷和頂角為136°的金剛石方形錐壓入器壓入材料表面，用材料壓痕凹坑的表面積除以載荷值，即為維氏硬度值(HV)。

●HL手提式硬度計，測量方便，利用沖擊球頭沖擊硬度表面后，產(chǎn)生彈跳；利用沖頭在距試樣表面1mm處的回彈速度與沖擊速度的比值計算硬度，公式：里氏硬度HL=1000×VB（回彈速度）/VA（沖擊速度）。●目前最常用的便攜式里氏硬度計用里氏（HL）測量后可以轉(zhuǎn)化為：布氏（HB）、洛氏（HRC）、維氏（HV）、肖氏（HS）硬度?；蛴美锸显碇苯佑貌际希℉B）、洛氏（HRC）、維氏（HV）、里氏（HL）、肖氏（HS）測量硬度值。時代公司生產(chǎn)的TH系列里氏硬度計就有此功能，是傳統(tǒng)臺式硬度機的有益補充！”（詳細(xì)情況請點擊《\o"里氏硬度計TH140/TH160/HLN-11A/HS141便攜式系列"里氏硬度計TH140/TH160/HLN-11A/HS141便攜式系列》）洛氏硬度(HRC)一般用于硬度較高的材料，如熱處理后的硬度等等。2、HB-布氏硬度：一般用于材料較軟的時候，如有色金屬、熱處理之前或退火后的鋼鐵。布式硬度(HB)是以一定大小的試驗載荷，將一定直徑的淬硬鋼球或硬質(zhì)合金球壓入被測金屬表面，保持規(guī)定時間，然后卸荷，測量被測表面壓痕直徑。布式硬度值是載荷除以壓痕球形表面積所得的商。一般為：以一定的載荷(一般3000kg)把一定大小(直徑一般為10mm)的淬硬鋼球壓入材料表面，保持一段時間，去載后，負(fù)荷與其壓痕面積之比值，即為布氏硬度值(HB)，單位為公斤力/mm2(N/mm2)。（關(guān)于布式硬度(HB)詳細(xì)情況請點擊《\o"布氏硬度機(計)HB-3000B/TH600"布氏硬度機(計)HB-3000B/TH600》）

3、洛式硬度是以壓痕塑性變形深度來確定硬度值指標(biāo)。以0.002毫米作為一個硬度單位。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。它是用一個頂角120°的金剛石圓錐體或直徑為1.59、3.18mm的鋼球，在一定載荷下壓入被測材料表面，由壓痕的深度求出材料的硬度。根據(jù)試驗材料硬度的不同，分三種不同的標(biāo)度來表示：

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)。

HRB：是采用100kg載荷和直徑1.58mm淬硬的鋼
