一种消除喷涂涂层孔隙率的方法
摘要：
本发明提供一种消除喷涂涂层孔隙率的方法，属于喷涂涂层封孔技术领域。本发明所述方法采用电磁感应加热的原理加热喷涂基体，基体热传导加热涂层；或者通过电磁感应直接加热涂层，当涂层温度达到熔点40%～90%时，在涂层表面施加压力，消除涂层的孔隙率，提高涂层的致密度，其中，涂层材料的熔点要低于基体熔点。喷涂技术制备涂层的原理会使涂层有一定的孔隙率，现有的方法都不能有效的消除涂层的孔隙率。采用本发明的技术，在电磁感应加热同时对涂层施加压力，可以消除孔隙率，增加涂层的综合力学性能，从而提高涂层的寿命和工作效率。
摘要（英）：

The invention provides a method for eliminating the porosity of a sprayed coating and belongs to the technical field of sprayed coating hole sealing. According to the method, a spraying substrate is heated through an electromagnetic induction heating principle, and the coating is heated through substrate heat conduction; or the coating is heated directly through electromagnetic induction, when the temperature of the coating reaches 40%-90% of the melting point, pressure is exerted on the surface of the coating, the porosity of the coating is eliminated, and the compactness of the coating is improved, wherein the melting point of a coating material is lower than the melting point of the substrate. Through the principle that the spraying technology is used for preparing the coating, the coating can have a certain porosity, while existing methods cannot effectively eliminate the porosity of the coating. With the technology of the method, the pressure is exerted on the coating while electromagnetic induction heating is conducted, the porosity can be eliminated, the comprehensive mechanical properties of the coating can be improved, thus the life of the coating is prolonged, and the work efficiency of the coating is improved.
