YD-4.9J渗透型液体硬化剂表面硬度试验仪

一、简介：

表面硬度试验仪适用于渗透型液体硬化剂的表面硬度测量。表面硬度原理是弹簧将规定的能量通过钢球冲击材料表面，通过测量试件表面的压痕直径来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、组成：

压痕硬度测试仪，由压球、压头、冲击杆、外壳、冲击和弹簧组成。
