显微测厚仪测试原理（系统如何实现高精度的测量）◆Crater on the coating surface using a precise borer bit.

精密的打孔装置在样品表面一次性形成一个深度达到基材的圆润的微孔

◆A shallow hole generated by the borer bit reveals each different coating layer from the substrate to the top coating.， Through a video microscope and high -resolution monitor， magnified bored-hole can be displayed and examined; The magnified crater displays each coating layer from the substrate to the finish coating layer.

如图一所示，通过微孔展示的经光学显微系统和软件处理的从基材到里层和表层的层间结构

◆The image on the screen can be magnified 400 times.

显微光学系统可以将微孔高保真放大至400倍

◆The thickness measurement of the coating layer is made by lining the crosslines (4 crosslines， 8 crosslines) from the beginning point to the ending point and measuring the distance between the 2 points with digital micrometer.

各涂镀层的厚度通过在4个座标方向或者8个座标方向上的数字测距来精确得到

◆The actual thickness of the coating layer measured can be obtained by dividing the measured distance by 10. (Feature 1)

如图二所示，a和b分别表示了两个涂层的厚度
