硬度試驗簡介自1722年歐洲工業(yè)**時期雷奧姆爾提出金屬硬度，并首先應用了礦物對金屬進行刻劃的初始硬度試驗以來的幾百年間，人類提出了幾百種測量金屬硬度的方法。通過長時間的實際應用，有些測量方法因為測量條件苛刻、程序繁瑣或精度不高等原因被歷史所慢慢淘汰。現(xiàn)在普遍應用的測量方法大多是使用方便且測試結果準確的測量方法。硬度試驗方法分類：1按試驗力的施加速度可分為1、靜力試驗法此試驗方法在施加試驗力時是緩慢且無沖擊的。硬度測量的結果主要依據(jù)被測試件表面的壓痕深度來決定。在一定的試驗力及試驗條件下，壓痕越大其硬度值越小。如常用的布氏、洛氏、維氏等硬度試驗法都是靜力試驗法。2、動力試驗法其施加試驗力的特點是動態(tài)的具有沖擊性的，包括肖氏、里氏、錘擊和彈簧加力試驗方法等。2按試驗力的大小分類1、宏觀硬度試驗法試驗力≥5kgf；2、小負荷硬度試驗法試驗力在；3、顯微硬度試驗法試驗力在；4、超顯微硬度試驗法試驗力∠；5、納米級硬度試驗法試驗力∠50nN。3按試驗的溫度分類1、常溫硬度試驗法可在常溫下進行；2、低溫硬度試驗法在零下以下某一特定溫度下進行；3、高溫硬度試驗法在室溫以上某一特定溫度下進行的高溫硬度試驗法。先進硬度機品牌排行硬度計調(diào)整后，開始測量硬度時，***個測試點不用。</p><div
