Problems solved by technology

[0004] Existing test methods for film bonding performance, such as traditional scratch test and Rockwell hardness test, are often unable to apply impact and tangential stress at the same time, especially based on the stress state of the material under working conditions. Targeted evaluation of film bonding properties under stress

Embodiment 1

[0033] like figure 1 As shown, the reciprocating inclined impact slip tester includes a punch 2, a sample stage 3, a base 6 and a rocker 7, wherein,

[0034] The rocker 7 is bent, and the angle formed by bending the rocker 7 is 150°-160°, and the upper surfaces of the rocker 7 belong to two intersecting planes respectively; The rocker 7 is connected to the base 6 through a bearing, and the rocker 7 is used to rotate around the bearing to change the relative positional relationship between the rocker 7 and the base 6;

[0035] The sample stage 3 is arranged on the rocker 7, and is located on the upper surface of the rocker 7 belonging to one plane in the two intersecting planes; above the upper surface of the rocker 7 belonging to the other plane in the two intersecting planes A fixing mechanism is provided; the fixing mechanism is used to limit the rotation angle of the rocker 7 around the bearing, and is used to adjust the rotation angle of the rocker 7 around the bearing, a...

Abstract

The invention discloses a reciprocating type oblique impact slide tester. The reciprocating type oblique impact slide tester is characterized by comprising a punch, a sample table, a supporting plate and a rocker, the preset relative position relation between the rocker and the supporting plate is kept through a fixing mechanism when the punch does not exert pressure on the sample table within a cycle of reciprocation, the rocker is driven by the punch to rotate around a bearing when the punch exerts pressure on the sample table, and the rocker rotates around the bearing through the fixing mechanism when the punch stops exerting pressure on the sample table so that the preset relative position relation between the rocker and the supporting plate can be restored and kept till the punch exerts pressure on the sample table again. By means of the tester, the stress state under the material working condition can be effectively simulated, the failure mechanism of obtained failed thin film materials is better matched with the failure mechanism of thin films in the actual working state, and the thin film combination performance result obtained according to the failed thin film materials has higher reference application value.

Description

technical field [0001] The invention belongs to the technical field of material bonding performance testing, and more specifically relates to a reciprocating inclined impact slip tester, which is especially suitable for evaluating the bonding performance of a hard film and a substrate. Background technique [0002] Surface strengthening treatment is a commonly used process in mechanical manufacturing. Its purpose is to obtain higher mechanical and physical properties on the entire or part of the surface of the workpiece, such as hardness, wear resistance, fatigue resistance, thermal conductivity and corrosion resistance. Sex, etc., and can increase the appearance. Among them, the hard film coating material is one of the very important methods of surface strengthening treatment. However, the most important factor affecting the service life of the hard film at present is the bonding performance of the film and the matrix material. Because the hardness, elastic modulus and ma...
