    摘要:

    孔隙在熱噴涂制備的涂層中較為常見,孔隙的形貌、大小、分布特征等對涂層的性能有著重要影響。因此,對熱噴涂涂層孔隙結(jié)構(gòu)特征的表征顯得尤為重要。本文對熱噴涂涂層孔隙結(jié)構(gòu)的表征方法進行了綜合評述,常用的圖像分析法包括通過光學(xué)顯微鏡、掃描電子顯微鏡、透射電子顯微鏡組織圖像中的孔隙結(jié)構(gòu)特征進行分析,浸滲壓入法,氣體吸附與解吸附,原子力探針接觸式測量,射線三維掃描成像(X射線、中子射線等),超聲波成像分析等。分析比較了各類方法的優(yōu)缺點以及適用范圍等,并對熱噴涂涂層孔隙結(jié)構(gòu)表征技術(shù)的發(fā)展進行了展望。

    Abstract:

    The pores existed commonly in the thermal sprayed coatings. The pore morphology, size and distribution took great effects on the performance of coatings. Therefore, it is very important to characterize pore structures of thermal sprayed coatings. In this work, the characterization means of thermal sprayed coatings’ pore structure were comprehensively reviewed. The often-used image analysis means of pore structure characterization included optical microscope, scanning electrical microscope and transmission electron microscope. Besides these, there were infiltration compression method, gas adsorption and desorption, contact measurement of atomic force probe, 3D ray scanning imaging including X-ray and neutron ray, ultrasonic imaging analysis, and so. The advantage and disadvantage of all kinds of pore characterization means were discussed. The application scopes of each mean were analyzed. The future characterization technology of thermal sprayed pore structure was prospected.
