一、簡(jiǎn)介：
表面硬度試驗儀適用于滲透型液體硬化劑的表面硬度測量。表面硬度原理是彈簧將規定的能量通過(guò)鋼球沖擊材料表面，通過(guò)測量試件表面的壓痕直徑來(lái)表征材料的表面硬度。
1. Introduction
The surface hardness tester is suitable for measuring the surface hardness of penetrating liquid hardeners. The principle of surface hardness is that the spring will impinge the specified energy on the surface of the material through a steel ball, and the surface hardness of the material is characterized by measuring the diameter of the indentation on the surface of the test piece.
二、組成：
壓痕硬度測試儀，由壓球、壓頭、沖擊桿、外殼、沖擊和彈簧組成。
