PCY-F composite material thermal expansion coefficient and coating residual stress comprehensive tester (relative method)

Detailed introduction

PCY-F composite material thermal expansion coefficient and coating residual stress comprehensive tester (relative method)
中国建筑材料科学研究总院专利, 湘潭湘仪仪器有限公司生产) ( Patent of China General Research Institute of Building Materials Science , produced by Xiangtan Xiangyi Instrument Co., Ltd.)
Professor Bao of China Building Materials Science Research Institute patent: The instrument can test the expansion coefficient and residual stress of the matrix, coating and composite samples of the composite material.
A(基体,不含涂层)和样品 B(含涂层,复合样品) 1. Prepare sample A (matrix, without coating) and sample B (with coating, composite sample)
B上 涂层的 横截面积 Ac和 基体的 横截面积 As Using a precision measuring tool, such as an optical microscope, the cross-sectional area Ac of the coating on the sample B and the cross-sectional area As of the substrate are measured, respectively . (Requires input before experiment). 获取样品 A (基体) 的热膨胀系数 Under the same experimental environment, simultaneously obtain the thermal expansion coefficient of sample A (substrate) B (复合体) 的热膨胀系数 , And the thermal expansion coefficient of sample B (composite) 利用样品 A和样品B的热膨胀系数结果计算涂层的热膨胀系数 ; Calculate the thermal expansion coefficient of the coating using the thermal expansion coefficient results of samples A and B .
2. Test two expansion coefficients and calculate the coating expansion coefficient. There are three expansion coefficients :

A( 基体 的热膨胀系数, : Thermal expansion coefficient of sample A ( matrix ) , 样品 B 复合体)的热膨胀系数 : Thermal expansion coefficient of sample B ( composite) , : Thermal expansion coefficient of the coating of the target object.
3. The software makes a judgment:
in case 则残余应力为压应力,否则为拉应力 , 计算到涂层的残余应力值 MPa。 , The residual stress is compressive stress, otherwise it is tensile stress , and the residual stress value MPa of the coating is calculated .
