Why Need Sample Mounting? Small-sized samples are often encountered during metallographic observation, so the samples are often mounted for easy grinding and polishing. To sum up, the applications of mounting mainly include the following aspects: Protect the Operator: It is convenient to hold thin, ... Read More

What are the factors that affect the fatigue strength of materials? Fatigue fracture often starts from the weakest place. If there are defects inside the material, such as cracks, brittle inclusions, etc., fatigue may start from these internal weak places. If the internal structure and performance ... Read More

What Is Dew Point? In simple terms, the dew point is the temperature at which the air can no longer hold all of its water vapor so that some of that vapor condenses into liquid water, forming dew or frost. More technically, it is a meteorological term that refers to the temperature to which air must ... Read More

Kinds of Rockwell Hardness Scales Initially, 15 scales were created using a 10 kg preliminary force; 60, 100 or 150 kg total test forces combined with diamond; 1⁄16, 1⁄8, 1⁄4 and 1⁄2-inch diameter ball indenters; and 0.2 millimeter per Rockwell point. These forces are called the Regular Rockwell ... Read More

R, Saturation barrel, manually refill water: tap water or purified water, require clean. S, Machine cover supporting frames:：Support cover use. T, Water inlet: saturated barrels and test chamber heating water from this port automatically supply, require clean water free of impurities, the water ... Read More

Does The Environment Affect Microhardness Testing Because of the light loads utilized in microhardness testing, vibration can contribute to loading accuracy. Even if the part is not impacted during loading, the oscillation of the indenter or the test specimen can cause the indenter to work its way ... Read More

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
