Corrosion Fatigue Fracture A fracture of a metal component caused by the combined action of cyclic stress and a corrosive medium is called corrosion fatigue fracture. Compared with ordinary fatigue fracture (caused only by cyclic stress), a corrosive environment weakens the material through chemical ... Read More

Fast Evolution of Coating Thickness Gages Today's thickness gages also are more simplified, and are far more advanced and sensitive than in years past. Understanding what equipment is available and how to use it is critical to ensuring process control, product quality and cost control. Depending on ... Read More

Principle of Metallographic Electrolytic Corrosion Instrument The metallographic electrolytic corrosion instrument is an instrument used for surface treatment and observation of metal samples, and is widely used in materials science, metallurgy and metal processing. This article will introduce the ... Read More

What Is Centrifugation? Centrifugation is the process of concentrating the natural forces that act on all particles of different densities to accelerate the natural process of separation. It is what separates the particles by density in the test tube. Centrifugation can occur with either filtration ... Read More

What is Contact Fatigue of Materials? Under high cyclic contact stress, small areas on the surface of a material experience local metal spalling, forming pitting and indentations, which eventually leads to component failure. This is called contact fatigue failure. Contact fatigue mainly occurs in ... Read More

How to Place Samples When Using Temperature Test Chamber? How to place the test product when using a high and low temperature test chamber? It is well known that a high and low temperature test chamber with a large capacity can accommodate more test products, while a small capacity test chamber can ... Read More

Vibration Fatigue Fracture When a part is in operation, it often undergoes back-and-forth reciprocating motion around its equilibrium position, which is mechanical vibration. Mechanical vibration is often harmful, as it can significantly reduce the performance and service life of machine parts. ... Read More

Differences Between Semi-auto and Fully-auto 2D Vision Measuring Machine 2D image measuring instrument is a device used to measure and detect the size and shape of a plane. It can obtain the required measurement results by shooting the image of the target object, analyzing and processing the image. ... Read More

Application and Using of Metallographic Cutting Machine The metallographic cutting machine is a commonly used equipment in metallographic laboratories for cutting and sampling metal materials. It is mainly used in metallographic microstructure analysis, quality control of metal materials, and ... Read More

What is Metal Low-Cycle Fatigue Fracture? Parts that experience low-cycle fatigue fracture are subjected to forces that are close to or exceed the yield strength of the material, with a relatively low loading rate, usually measured in minutes, hours, or even longer periods. One characteristic of low... Read More
