Embodiment approach

[0046] In a further embodiment of the present invention, the surface roughness of the above-mentioned foot gold jewelry is measured to determine whether different regions of the same foot jewelry have the same or similar roughness.

[0047] In a further embodiment of the present invention, the surface roughness of the above-mentioned foot gold jewelry is measured in different regions of the same foot gold ornament, and the surface roughness of different regions is compared with the surface roughness of the predetermined region. To determine whether the surface roughness of the region meets the requirements.

[0048] In a further embodiment of the present invention, the measurement of the surface roughness of the above-mentioned foot gold jewelry is performed on one or more selected regions of different foot gold jewelry to determine whether or not there is the same or similar surface roughness between different foot gold ornaments. , That is, whether there is average, good control...

Abstract

The invention discloses a method for measuring the surface roughness of a pure gold ornament and a sequencing method. The method comprises steps of selecting a sampling region on the surface of the pure gold ornament, and enabling the sampling region to comprise a plurality of particles; measuring the sizes of a plurality of particles to obtain a plurality of measurement values, and performing reduction on a plurality of measurement values to obtain a plurality of reduction values; wherein the measurement value is multiplied by two to obtain a first intermediate value, the unit number of the first intermediate value is rounded to obtain a second intermediate value, and the second intermediate value is divided by two to obtain a reduction value; and taking the median value of the plurality of reduction values as the surface roughness of the pure gold ornament. The invention provides a repeatable and reliable method for detecting the surface roughness of the pure gold ornament, and surface roughness of the pure gold ornament can be objectively and accurately detected.

Description

Technical field [0001] The present invention relates to the technical field of surface roughness of foot gold ornaments, and more particularly to a method of measurement of surface roughness of foot gold ornaments. Background technique [0002] The precious metal includes gold, silver and platinum group metal, which is very small in the crustal content and dispersed. Precious metal materials are the main basic materials for jewelery and crafts, and gold discovery and development history is very long. [0003] Gold has a beautiful golden gloss, chemical stability, but due to the different production processes, it will exhibit a different surface characteristics of roughness. [0004] In the sale of the foot gold jewelry, the surface exhibited different roughness surfaces, and the surface of the roughness or too low will affect the overall appearance of the foot gold jewelry. [0005] In the past, the discrimination of the surface roughness of the gold jewelry was evaluated by huma...
