Abstract

The invention discloses a clamp for detecting friction corrosion of a coating. The clamp comprises: a support unit comprising a clamp base, a sliding guide rail mounted on the clamp base, and a sliding chute connected with the sliding guide rail in a matched manner, wherein the sliding chute is mounted below a bottom plate; and a clamp unit comprising a containing part fixedly installed on the bottom plate, wherein one face of the containing part is sunken inwards to form a clamping groove, and two symmetrically-arranged V-shaped blocks are installed at the bottom of the clamping groove. The clamp is compact and reasonable in structure and convenient to operate, a set of friction corrosion combined clamp capable of containing corrosive liquid is designed by applying the clamp for friction corrosion detection of the coating, and the corrosive liquid can be put into a cuboid container to simulate the actual abrasion working condition of engineering parts.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a fixture for coating friction and corrosion detection. Background technique [0002] The fixture for testing the wear resistance of coating samples is a device installed on the friction and wear testing machine to clamp the workpiece and guide the alignment of the force sensor. Its function is to ensure the position of the sample relative to the friction and wear testing machine and the force sensor Relatively correct, and reliably clamp the workpiece; the characterization of the coating surface has always existed in the field of surface strengthening. Generally speaking, the surface strengthening technology can be divided into laser cladding, brazing, plasma cladding, etc. All these are to prepare a layer of strengthening coating on the surface of the original substrate to enhance the mechanical and chemical properties of the original material surface. In the field of practical enginee...
