摘要

在手表生产中，由于机芯零件的电镀层厚度难以控制，影响手表的装配精度、走时准确和使用寿命。尤其在每年黄梅季节，常发现零件生锈报废和手表返修除锈，这不仅影响手表美观，而且影响手表的产量、质量和成本。为了有效地控制手表零件的镀层厚度和贵重金属用量，并能指导电镀工艺，迫切需要对手表零件镀层厚度作快速无损测量。

Abstract

By means of the X-ray fluorescence technique

the thickness of a plating layer can be measured relatively. With the aid of a microprocessor

the value of the measured(µm) can be printed out directly. The objects of measurement can be cobalt-nickel plating layer on the base of steel or brass and gold plating layer on the base of nickel white copper. The measuring range of thickness is usually 1—6µm with an error of less than ±0.3µm

and the area for the measurement is usually no less than 2 mm in diameter.
