Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Combine figure 1, a hardness testing device for material science, including base 1, the one end of base 1 is equipped with L type pole 2, the one end that base 1 was kept away from to L type pole 2 is equipped with pneumatic cylinder 3, the output of pneumatic cylinder 3 is equipped with pressure sensor 4, it is equipped with detachable detection head 5 to connect on the pressure sensor 4, be equipped with the plate body 6 that the symmetry set up on the base 1, be equipped with mobilizable horizontal pole 7 on the plate body 6, the one end that horizontal pole 7 is close to base 1 is equipped with mutually supported extension board 8, be equipped with controller 9 on the base 1, controller 9 respectively with pneumatic cylinder 3 and 4 electric connection of pressure sensor.
The hardness is divided into: (ii) scratch hardness. The method is mainly used for comparing the hardness of different minerals, and comprises the steps of selecting a rod with one hard end and one soft end, scratching the tested material along the rod, and determining the hardness of the tested material according to the position where scratches appear. Qualitatively, a hard object will scratch longer and a soft object will scratch shorter. ② press-in hardness. The method is mainly used for metal materials, and the method is that a specified pressure head is pressed into the tested material by using a certain load, and the hardness of the tested material is compared according to the local plastic deformation of the surface of the material. Due to the difference of indenter, load and load duration, the press-in hardness is various, mainly including Brinell hardness, Rockwell hardness, Vickers hardness, microhardness and the like. And thirdly, rebound hardness. Mainly for metal materials, by making a special small hammer drop freely from a certain height to impact a test sample of the tested material, and determining the hardness of the material according to the amount of strain energy stored (and then released) in the test sample during the impact process (measured by the rebound height of the small hammer).
