Microhardness traverse line of indentations – are commonly used to check for effective case depth on parts that have been carburized, nitrided, induction hardened or surface treated. It can check the hardness of thin coatings or characterize hardness variation through a cross-section.
Microhardness Testing Capabilities :
At VSP, our microhardness testing Laboratory equipment can test Vickers scales in loads ranging from 0.1 kg (100 grams) to 1 kg (1,000 grams).
Combined with high-quality optics, our microhardness testing equipment is uniquely capable of checking:
♦ Case depth and hardness in multiple locations
♦ Coating hardness
♦ The hardness of small diameter wire of a thin gauge sheet
♦ The hardness of a phase or constituent in a matrix
Our state-of-the-art auto-turrate machine with software allows for programmable patterns and locations that provide ultimate flexibility and microhardness testing speed. Our multi-specimen holder can program many locations and patterns in a sample, making it optimal for production work.
Our expert metallurgists set up various pattern and location combinations and let the instrument go to work. That reduces your testing costs and allows for quick turn-around time.
We can contour a curved surface and make a colour map of any cross-section. VSP maintains strict calibration intervals, and we verify the accuracy and precision of the machine before each test with NIST traceable reference standards at individual test loads.
