Ball mark type coating thickness meter

Abstract

The invention discloses a ball mark type coating thickness meter comprising a grinding ball, a rotating arm, a motor, a detection station and an instrument rack, wherein the rotating arm, the motor and the detection station are arranged on the instrument rack; the grinding ball is arranged between the rotating arm and the detection station and is pressed on the surface of the detection station; the motor is in mechanical driving connection with the rotating arm; the grinding ball is driven by the motor through the friction of a trapezoid groove of the rotating arm to carry out press grinding on the surfaces of samples; and the coating thickness is measured and calculated according to grinding mark graphic data. The invention has the advantages of short measuring period, high speed, small size of the equipment, low cost and simpleness and convenience for operating and sampling, and is especially suitable for quickly measuring the coating thickness having low requirement for the coating thickness.

Description

technical field [0001] The invention relates to a coating thickness measuring instrument, in particular to a ball trace type coating thickness measuring instrument. Background technique [0002] At present, the surface modification of materials has been widely used in many fields such as industry, agriculture, and national defense. As a method of surface modification, the coating process can effectively change the properties (physical and chemical properties) of the material surface, thereby Improving various properties of the workpiece surface, such as improving the hardness and wear resistance of the workpiece surface, improving the corrosion resistance and high temperature resistance of the workpiece surface, and prolonging the service life of the workpiece has attracted people's attention. So far, using various ion plating processes, such as multi-arc ion plating process, magnetron sputtering ion plating process, etc., people have developed a variety of coating products,...

AI Technical Summary

Problems solved by technology

[0004] There are many methods to detect the thickness of the coating. At present, commonly used instruments such as profilometers and step gauges are used for measurement, or scanning electron microscopes are used to directly observe and measure the coating section, but there are many disadvantages in using these methods, such as: large equipment volume, equipment High cost, long measurement cycle, inconvenient sample preparation, etc., cannot meet the requirements of convenient and rapid detection of coating thickness in coating industrial production
