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 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

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

What Is a Centrifuge? A centrifuge is a machine that uses centrifugal force to separate the contents of a sample based on their density. When the centrifuge spins, it creates a strong centrifugal force. Though separation would eventually happen naturally with Earth’s gravity, the centrifuge machine ... Read More

Types of Rockwell Tests There are two types of Rockwell tests: • Regular Rockwell: the minor load is 10 kilograms of force (kgf) and the major load is 60, 100 or 150 kgf. • Superficial Rockwell: the minor load is 3 kgf and major load is 15, 30 or 45 kgf. In both tests, the indenter may be either a ... Read More
