本发明涉及高温合金防护涂层抗热震性能测试技术领域，具体涉及一种带涂层试片抗热震性能测试装置及方法。The invention relates to the technical field of thermal shock resistance testing of high-temperature alloy protective coatings, and specifically to a thermal shock resistance testing device and method for coated test pieces.
背景技术Background technique
热障涂层具备良好隔热、耐磨、耐蚀性，广泛用于航空发动机或燃气轮机热端部件热防护领域。热端部件服役于恶劣工况下，热应力或热疲劳过大，易导致部件过早失效，而热障涂层能实现高温热防护、减少热量传递，很好保护热端部件安全，其质量优劣直接关系到部件服役可靠性。热障涂层使用过程中，若环境温度发生剧烈变化，抗热震性能较差的涂层将产生裂纹，甚至剥落损坏。热障涂层制备完毕后，需对其抗热震性能进行测试，根据抗热震性能优劣更好指导涂层制备质量及部件服役可靠性评估。Thermal barrier coating has good heat insulation, wear resistance and corrosion resistance, and is widely used in the field of thermal protection of hot end components of aero engines or gas turbines. Hot-end components serve in harsh working conditions. Excessive thermal stress or thermal fatigue can easily lead to premature component failure. The thermal barrier coating can achieve high-temperature thermal protection, reduce heat transfer, and protect the safety and quality of hot-end components. The quality is directly related to the service reliability of the components. During the use of thermal barrier coatings, if the ambient temperature changes drastically, coatings with poor thermal shock resistance will crack or even peel and be damaged. After the thermal barrier coating is prepared, its thermal shock resistance needs to be tested. Based on the thermal shock resistance, it is better to guide the coating preparation quality and component service reliability evaluation.
现有抗热震性能测试流程为：首先将喷涂有热障涂层的试片做标记并拍照，记录最初表面外貌；后将试片放入马弗炉中加热到合适温度并保温一定时间，达到规定时间后取出试片并放入常温水中急冷一定时间，表面干燥并观察涂层表面是否脱落并拍照，定义此为一次循环；进行多次循环试验直至脱落面积达到预定面积时终止热震试验。The existing thermal shock resistance test process is: first, mark and take pictures of the test piece sprayed with thermal barrier coating, and record the initial surface appearance; then put the test piece into the muffle furnace, heat it to the appropriate temperature and keep it warm for a certain period of time. After reaching the specified time, take out the test piece and put it into normal temperature water for a certain period of time. Dry the surface and observe whether the coating surface peels off and take pictures. This is defined as a cycle; conduct multiple cycle tests until the peeling area reaches the predetermined area and terminate the thermal shock test. .
由于试验过程穿插观察、拍照、加热、保温、冷却、干燥、观察、拍照并反复进行此过程，试验过程耗时、耗力且人为操作因素多，人为误差概率高；而且试验中开始出现涂层脱落、涂层脱落面积大小、试验操作工艺准确和一致性等人为判断因素较多，测试的涂层抗热震性能数据精确度较低。Since the test process is interspersed with observation, photography, heating, insulation, cooling, drying, observation, photography, and repeating this process, the test process is time-consuming, labor-intensive, has many human operating factors, and the probability of human error is high; and coatings began to appear during the test There are many human judgment factors such as peeling, the size of the coating peeling area, the accuracy and consistency of the test operation process, etc., and the accuracy of the thermal shock resistance performance data of the tested coating is low.

When the heating operation is performed, the test piece installation station on the other end The test piece body corresponds to the cooling assembly to perform the cooling operation. The default appearance is that the surface coating peeling area of the sample body is greater than 15%.
具体地，在试验前首先确保蓄水池内恒温流动的冷却水的水位低于X型框架下端平面载物台的高度，使得X型框架下端的载物台旋转至下方时能够被浸入到冷却水中。将处理好的带涂层试样片分类标记并装配至上下两端的作为试验安装工位的固定试样卡槽，不开流动冷却水和感应线圈加热，只打开旋转电机和图像采集组件完成试片本体加热前的拍照，记录最初表面外貌。两个载物台上的所有试片本体记录最初表面形貌完成后打开流动冷却水和感应线圈加热，加热至感应温度时，测试试验正式开始。Specifically, before the test, first ensure that the water level of the constant-temperature flowing cooling water in the reservoir is lower than the height of the flat stage at the lower end of the X-shaped frame, so that the stage at the lower end of the X-shaped frame can be immersed in the cooling water when it is rotated downward. . Classify and mark the processed coated specimens and assemble them into the fixed specimen slots at the upper and lower ends as test installation stations. The flowing cooling water and induction coil heating are not turned on, and only the rotating motor and image acquisition components are turned on to complete the test. Take a photo of the film body before heating to record the initial surface appearance. After the initial surface morphology of all test pieces on the two stages is recorded, the flowing cooling water and induction coil heating are turned on. When heated to the induction temperature, the test test officially begins.
对感应线圈内的载物台上的多个试片本体进行加热，加热到合适温度并保温一定时间；另一个载物台上的多个试片本转至恒温冷却水内，冷却一定时间，一次实现两批试片同时进行加热和冷却；同时控制旋转电机的转动角度能够调整试片本体加热面或冷却面角度，充分快速加热或冷却。旋转电机工作带动安装支架旋转，已加热的载物台转至恒温冷却水内进行冷却一定时间，同时之前冷却的载物台上的试片本体转至感应线圈内加热。然后，第一次加热的载物台上的试片本体转至带有图像采集组件一侧时，调整载物台平面角度以便于对试片涂层进行充分观察，即为该批试片本体的一次循环，两批次重复该过程可进行多次循环并观察，直至获得最终试验结果。试验完成后再换两批次的试片本体继续重复该操作即可。The multiple test pieces on the stage in the induction coil are heated to a suitable temperature and kept warm for a certain period of time; the multiple test pieces on another stage are transferred to constant temperature cooling water and cooled for a certain period of time. Two batches of test pieces can be heated and cooled at the same time; simultaneously controlling the rotation angle of the rotating motor can adjust the angle of the heating surface or cooling surface of the test piece body to fully and quickly heat or cool. The rotating motor drives the mounting bracket to rotate. The heated stage is transferred to the constant-temperature cooling water for cooling for a certain period of time. At the same time, the test piece body on the previously cooled stage is transferred to the induction coil for heating. Then, when the test piece body on the stage heated for the first time is turned to the side with the image acquisition component, the plane angle of the stage is adjusted to fully observe the test piece coating, which is the batch of test piece body. This process can be repeated for two batches for multiple cycles and observed until the final test results are obtained. After the test is completed, change two batches of test piece bodies and continue to repeat the operation.
在试验过程中，图像采集组件不断采集试片本体的图像，以观测试片本体的样貌，在其样貌变为预设样貌后，完成试验，对试片本体取下进行后续检测。在进行试验过程中，通过转动安装支架即可完成对试片本体加热操作和冷却操作的切换，在判断试片本体的样貌时，通过图像采集组件进行拍摄后输出到装置外进行判断，无需对试片本体进行操作，使得试片本体在试验过程中始终处于装置内的试片安装工位上，能大大减少人为因素对试片本体的影响，提升测试得到的性能数据精确度。During the test process, the image acquisition component continuously collects images of the test piece body to observe the appearance of the test piece body. After its appearance changes to the preset appearance, the test is completed and the test piece body is removed for subsequent inspection. During the test, the heating operation and cooling operation of the test piece body can be switched by rotating the mounting bracket. When judging the appearance of the test piece body, the image acquisition component is used to capture the image and output it to the outside of the device for judgment, without the need for The test piece body is operated so that the test piece body is always at the test piece installation station in the device during the test, which can greatly reduce the impact of human factors on the test piece body and improve the accuracy of the performance data obtained from the test.
