Oxide film hardness test – hard
Selection of the meter
Oxide film, also known as passivation film, is formed due to metal surface passivation. It creates a dense protective layer with excellent coverage.
Most passivation films are composed of metal oxides.
The oxide film plays an essential role in metal materials by forming an oxide layer on the surface that prevents further oxidation, helping to prevent corrosion.
It is widely used in various fields such as semiconductors, automotive, aerospace, and precision instruments.
In many industries, the requirements for oxide films are quite high. There are numerous tests needed, including thickness measurement, which is relatively easy to perform. However, hardness testing remains a challenge due to the thinness of the oxide layer.
Here is a complete solution for oxide film hardness measurement:
For oxide thickness ≥8μm
HV-1BM Oxide Film Hardness Test System
Sample preparation includes cutting, embedding, and grinding.
HV-1BM Oxide Film Hardness Test System – Hardness Testing Part
This system is designed for heat-treated materials, carburized layers, quenched hardened layers, surface oxide films, coatings, steel, non-ferrous metals, and small or thin parts.

HV-1BM Oxide Film Microscopic Vickers Hardness Tester
The HV-1BM is the key equipment for measuring oxide film hardness. It features an LCD display screen, allowing users to select test forces (HV or HK) through the control panel. The light source brightness can be adjusted infinitely. When D1 and D2 values are entered via the eyepiece, the hardness value is directly displayed on the screen.
