What is the Hardening Case Depth? In powder‑coating and heat‑treatment processes, the case depth (often called the hardened layer thickness) is a critical parameter that determines wear resistance and fatigue life of a component. The depth is primarily governed by the diffusion of carbon (or other ... Read More

What is Ultrasonic Flaw Detector? Ultrasonic flaw detector is a device that use sound propagation method for the detection of flaws in many materials. The basic use of ultrasonic flaw detector is done in many engineering processes. This is used in the process of detection of material surfaces. ... Read More

Charpy V-Notch Impact Tester Core Principle: A pendulum of known weight drops from a fixed height, hitting and breaking a standard specimen. The difference between the final height the pendulum swings to after passing through the specimen and the initial height reflects the energy absorbed by the ... Read More

Error and Repeatability of Micro Vickers Hardness Test Below is the table of Error and Repeatability of Micro Vickers Hardness Tester was cited from ASTM E384. Read More

Common Problems in Microhardness Testing Microhardness testers are delicate instruments. Extremely light forces (typically from 10 to 1,000 g.) must be accurately applied, and the resultant impressions (some as small as 10 microns) must be precisely measured under high magnification. And so there ... Read More

The thickness of the test specimen shall be such that no bulge or marking showing the effect of the force appears on the side of the specimen opposite the impression. In any event the thickness of the specimen shall be at least one and one half times the length of the diagonal. When laminated ... Read More

What is Depth of Field (DOF) ? Microscope depth of field (DOF), also called focus range or effective focus range, is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the ... Read More
