18、30831045.788868.496859433.63203113134689068.5976硬度換算公式: 1.肖氏硬度(HS)=勃式硬度(BHN)/10+12 2.肖式硬度(HS)=洛式硬度(HRC)+15 3.勃式硬度(BHN)= 洛克式硬度(HV) 4.洛式硬度(HRC)= 勃式硬度(BHN)/10-3 洛氏硬度HRC和布氏硬度HB等硬度对照区别和换算硬度 是衡量材料软硬程度的一个性能指标。硬度试验的方法较多，原理也不相同，测得的硬度值和含义也不完全一样。最普通的是静负荷压入法硬度试验，即布氏硬度(HB)、洛氏硬度(HRA，HRB，HRC)、维氏硬度(HV)，橡胶塑料邵氏硬度(HA,

19、HD)等硬度其值表示材料表面抵抗坚硬物体压入的能力。最流行的里氏硬度（HL）、肖氏硬度(HS)则属于回跳法硬度试验，其值代表金属弹性变形功的大小。因此，硬度不是一个单纯的物理量，而是反映材料的弹性、塑性、强度和韧性等的一种综合性能指标。1、钢材的硬度 ：金属硬度(Hardness)的代号为H。按硬度试验方法的不同，常规表示有布氏（HB）、洛氏（HRC）、维氏（HV）、里氏（HL）硬度等，其中以HB及HRC较为常用。 HB应用范围较广，HRC适用于表面高硬度材料，如热处理硬度等。两者区别在于硬度计之测头不同，布氏硬度计之测头为钢球，而洛氏硬度计之测头为金刚石。HV-适用于显微镜分析。维氏硬度(H

20、V) 以120kg以内的载荷和顶角为136的金刚石方形锥压入器压入材料表面，用材料压痕凹坑的表面积除以载荷值，即为维氏硬度值(HV)。 HL手提式硬度计，测量方便，利用冲击球头冲击硬度表面后，产生弹跳；利用冲头在距试样表面1mm处的回弹速度与冲击速度的比值计算硬度，公式：里氏硬度HL=1000VB（回弹速度）/ VA（冲击速度）。目前最常用的便携式里氏硬度计用里氏（HL）测量后可以转化为：布氏（HB）、洛氏（HRC）、维氏（HV）、肖氏（HS）硬度。或用里氏原理直接用布氏（HB）、洛氏（HRC）、维氏（HV）、里氏（HL）、肖氏（HS）测量硬度值。时代公司生产的TH系列里氏硬度计就有此功能，是

21、传统台式硬度机的有益补充！”（详细情况请点击里氏硬度计TH140/TH160/HLN-11A/HS141便携式系列 ）洛氏硬度(HRC)一般用于硬度较高的材料，如热处理后的硬度等等。2、HB - 布氏硬度：一般用于材料较软的时候，如有色金属、热处理之前或退火后的钢铁。布式硬度(HB)是以一定大小的试验载荷，将一定直径的淬硬钢球或硬质合金球压入被测金属表面，保持规定时间，然后卸荷，测量被测表面压痕直径。布式硬度 值是载荷除以压痕球形表面积所得的商。一般为：以一定的载荷(一般3000kg)把一定大小(直径一般为10mm)的淬硬钢球压入材料表面，保持一段时 间，去载后，负荷与其压痕面积之比值，即为布氏硬度值(HB)，单位为公斤力/mm2 (N/mm2)。 （关于布式硬度(HB)详细情况请点击布氏硬度机(计)HB-3000B/TH600 ）3、洛式硬度是以压痕塑性变形深度来确定硬度值指标。以0.002毫米作为一个硬度单位。当HB450或者试样过小时，不能采用布氏硬度试验而改用洛氏硬度计量。它是用一个顶角120的金刚石圆锥体或直径为1.59、3.18mm的钢球，在一定载荷下压入被测材料表面，由压痕的深度求出材料的硬度。根据试验材料硬度的不同，分
