里氏硬度是由瑞士LEEB博士1978年***提出的全新的硬度測(cè)量方法，它的定義是：用規(guī)定質(zhì)量的沖擊體在彈力作用下以一定速度沖擊試樣表面，用沖頭在距離試樣表面1mm處的回彈速度與沖擊速度之比計(jì)算出的數(shù)值，因LEEB博士提出而得名，故而叫里氏硬度。里氏硬度計(jì)的計(jì)算公式如下：HL=1000×Vb/Va,式中：HL————里氏硬度符號(hào)Va————球頭的沖擊速度，m/s；Vb————球頭的反彈速度，m/s。【布氏硬度】布氏硬度（BrinellHardness）的測(cè)定原理是用一定大小的試驗(yàn)力F(N)（力的單位通常為公斤力kgf，注：1kgf=，kgf即一千克的力的意思），把直徑為D（mm）的淬火鋼球或硬質(zhì)合金球壓入被測(cè)金屬的表面（圖1），保持規(guī)定時(shí)間后卸除試驗(yàn)力，用讀數(shù)顯微鏡測(cè)出壓痕平均直徑d(mm)，然后按公式求出布氏硬度HB值，或者根據(jù)d從已備好的布氏硬度表中查出HB值。校準(zhǔn)硬度計(jì)用的標(biāo)準(zhǔn)塊不能兩面使用，因標(biāo)準(zhǔn)面與背面硬度不一定一致。端淬硬度機(jī)批量定制</p><p
