Abstract
The utility model relates to a measuring device which is used for measuring the binding strength of a hot spray coating. At present, methods which are used for measuring the binding strength of the hot spray coating are frequently that the surface of a cylinder with the hot spray coating is firstly stuck with anther cylinder by adhesive and then the operation of tension measurement is used for calculating the binding strength. The measured result is easily influenced by the strength of the adhesive, which causes a great error. The utility model is composed of a plate body and a sliding shaft, wherein a hole is arranged in the middle part of the plate body and the upper part of the hole is conical and the lower part of the hole is cylindrical; the matched sliding shaft is arranged in the hole and the upper part of the sliding shaft is conical and the lower part of the sliding shaft is cylindrical. The hot spray coating is sprayed at the top end of the sliding shaft and the upper surface of the plate body; when the device measures, the sliding shaft is gradually applied load along the axial direction of the sliding shaft until pullout. The ratio of the load weight to the area of the top end of the sliding shaft is the measured value of the coating binding strength which is accurate and convenient.
Description
The utility model relates to a kind of measurement mechanism that is used to measure the thermally sprayed coating bond strength.
The bond strength of hot spray coating is to estimate the important parameter of thermally sprayed coating performance.The measurement mechanism of the thermally sprayed coating bond strength of using is after a periphery is finished thermal spray at present, and is bonding with bonding agent with another right cylinder, finishes tensile test then on tension tester, and then calculates bond strength.This measuring method directly is subjected to the intensity effect of bonding agent, and when Bond Strength of Coating is higher than the bond strength of bonding agent, this method can't provide actual measured value, easily produces bigger measuring error.
The purpose of this utility model is to provide a kind of novel thermally sprayed coating bond strength measurement mechanism.
The utility model is made of plate body and slide-bar, it is columniform hole for conical, bottom that the middle part of plate body has a top, the built-in top that matches with plate body is that circular cone, bottom are columniform slide-bar, and the upper surface of slide-bar top plan and plate body is in the same plane.During use metal is sprayed on the top end surface of plate body and slide-bar according to the requirement of spraying coating process, when measuring bond strength, plate body is supported, slide-bar is axially slowly loaded until pulling out along it, final loading size is the anchoring strength of coating measured value with the ratio of the apex area of slide-bar.
The utility model advantage is to use this device relatively easily to measure the bond strength of thermally sprayed coating.The thermally sprayed coating bond strength measurement accuracy and the reappearance of measurement data have repeatedly been improved.
Description of drawings:
Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
1 is plate body among the figure, the 2nd, and slide-bar, the 3rd, thermally sprayed coating.
Below in conjunction with accompanying drawing the utility model is described in further detail:
The utility model is made of plate body (1), slide-bar (2), it is columniform hole for conical, bottom that the middle part of plate body (1) has a top, a built-in top that matches is columniform slide-bar (2) for conical, bottom, the upper surface of the top plan of slide-bar (2) and plate body (1) is in the same plane, at the upper surface of plate body (1) and top end surface spraying one deck thermally sprayed coating (3) of slide-bar (2).During measurement, plate body (1) is supported, slide-bar (2) loading downwards can be finished the measurement of thermally sprayed coating bond strength.
Claims (1)
1, a kind of thermally sprayed coating bond strength measurement mechanism, it is characterized in that it is made of plate body (1) and slide-bar (2), it is columniform hole for conical, bottom that the middle part of plate body (1) has a top, and the built-in top that matches is columniform slide-bar (2) for conical, bottom, and the upper surface of the top plan of slide-bar (2) and plate body (1) is in same plane.
