Looking for Digital Micro Vickers Hardness Tester Suppliers in Chennai? At Modern Metallurgical & Scientific Services get accurate micro-hardness testing machines for metals, coatings, thin sections, heat-treated layers and precision components.
A Digital Micro Vickers Hardness Tester is a precision laboratory instrument used to measure the micro-hardness of metals, alloys, coatings, thin sections and small components. It applies a controlled diamond indenter load to a test surface and measures the resulting indentation through an optical microscope or digital imaging system.
Digital Micro Vickers Hardness Testers are widely used in metallurgical laboratories, quality-control departments, research institutions, automotive industries, heat-treatment facilities and engineering companies. Chennai suppliers offer models ranging from conventional digital systems to semi-automatic and fully automatic configurations.
Chennai Metco, for example, lists digital micro-Vickers hardness testers with automatic loading, dwelling and unloading, multiple test-force options from 10 gf to 1 kgf, digital displays, X-Y stages and data-output features.
A Micro Vickers Hardness Tester determines the hardness of a material using a diamond pyramid indenter. A small test force creates a microscopic indentation on the polished surface of the specimen.
The instrument measures the diagonals of the indentation and calculates the Vickers hardness value.
The digital version improves the testing process by providing electronic controls, digital displays, automatic test-force application and, depending on the model, data storage, printing and computer connectivity.
Micro-Vickers testing is especially useful where conventional hardness testing methods cannot provide suitable measurements because the sample is too small, thin or has a localized surface area.
The general testing process involves:
