Exploration of Sample Preparation for Metallographic Competition Based on Manual Polishing Method
Metallographic skills were a basic skill that students majoring in materials and it was also a key to understanding materials.Grinding was the basis of metallographic sample preparation,and this paper aimed to explore the methods to improve the grinding effect and efficiency of metallographic sample preparation.Through the in-depth analysis of the difficulties and defects of sample grinding,a method significantly to improve the preparation quality and efficiency of sample was proposed.This method has certain reference significance for the preparation of standard metallographic samples,and has a guiding significance for the participants of the metallographic competition,and also has a certain role in promoting the development of the field of materials science research.
