Method for processing computing microphase characteristic of ceramic glaze SEM image by using structure array

Abstract

Provided is a method for processing computing a microphase characteristic of a ceramic glaze SEM image by using a structure array. The method comprises a step 1 of reading a clear SEM gray value image; a step 2 of determining and selecting continuous areas with gray pixel value changes less than 10 from the head of the SEM image according to the split-phase information characteristic of the SEM gray value image, counting the number of the pixels in the areas, computing gray pixel mean values of the areas, and saving the gray pixel mean value and the number of the pixels of each area in a structure array a; a step 3 of ordering the structure array a according the number of the pixels of each member in the structure array a; a step 4 of writing a program to rewrite gray pixel mean value member values in the structure array a and to mark the outlines of all areas; a step 5 of determining and computing the split-phase microsphere shape information (roundness, radius, center of sphere and the like) and distance information (distance between two centers of sphere) of each marked SEM image; and a step 6 of analyzing a large number of SEM images with different temperatures and colors by the method, finding out a rule, and creating a model.

Description

technical field [0001] The invention belongs to the technical field of research on phase separation and color development of ceramic glazes, and relates to the research on the mechanism and rules of phase separation and color development of ceramic glazes, in particular to the derivation of the mathematical model of phase separation and color development of ceramic glazes, and specifically relates to a structure A method for array processing and calculation of microphase characteristics of SEM images of ceramic glazes. Background technique [0002] At present, judging from the basic and applied research results of phase-separated enamel, the status and importance of phase-separated glaze in art and display porcelain is beyond doubt. Although the depth and breadth of basic and applied research on phase-separated glazes in traditional ceramics are extremely limited, it is fascinating that ceramic glazes can present different colors as the phase-separated state changes. It is ...

Problems solved by technology

Due to the complex phenomenon of phase separation, according to the existing measurement methods, the information such as the shape of each microphase is generally measured manually based on the scanning electron microscope image (SEM), which has defects such as heavy workload, low efficiency, and inaccuracy.
