hardness testing造句

mechanical hardness testing machine for testing industrial materials

This paper presents a micro-hardness testing method, namely depth-hardness testing with nanometer scale.

Indentation methods of hardness testing comprise two principal groups.

hardness testing methods for rubber, vulcanized or thermoplastic

Method of Shore hardness testing for mill rolls

It was found that the surface roughness is significant in Brinell hardness testing, but has little influence on Rockwell hardness.

Analysis was performed on the crack zone by macroscopical, microscopical and hardness testing.

The Rockwell hardness tester is a precision measurement instrument in material and part hardness testing, which is often used in detection of materials, product and half-finished product.

By means of chemical composition analysis, hardness testing, non-metallic inclusion examination, metallographic examination, macro and micro-fractography fracture analysis were conducted.

The surface layers are characterized by means of the optical microscope, X ray diffraction, transmission electronic microscope, and micro hardness testing machine.
