一、概述数显液流测厚仪于1982年12月,由沈阳仪器仪表工艺研究所研制成功,并通过了部局组织的鉴定。鉴定认为,该仪器是国内首次根据原部颁标准JB2115-77《金属复盖层厚度试验方法,计时液流法》进行设计的,并达到了国内先进水平。用液流法测量金属镀层的厚度是一种广泛应用的镀层局部厚度的测量方法。这种方法用到的设备简单,操作方便,适用性强。这种方法对底基材质的导磁率变差和被测零件表面形状的变化均不敏感;此法还特别适用于其它方法难于测量的小型、异型零件(如螺纹等零件)。因此,在电镀工艺中,
First, an overview Digital flow thickness gauge in December 1982, by the Shenyang Institute of Instrumentation Technology successfully developed and adopted by the Ministry of Organization Identification. Identification that the instrument is the first time in accordance with the original issued JB2115-77 “metal cover thickness test method, timing flow method” to design, and reached the advanced domestic level. Measuring the thickness of a metal coating by the flow method is a widely used method of measuring the local thickness of a coating. This method used equipment is simple, easy to operate, applicability. This method is not sensitive to changes in the permeability of the substrate material and the shape of the surface of the part under test; this method is also particularly suitable for small, shaped parts (such as threads) that are otherwise difficult to measure. Therefore, in the plating process,
