Rockwell Hardness Testing of PEEK Polymer Composites
PEEK (polyetheretherketone) is a high-performance composite material made by combining PEEK resin with reinforcing materials such as carbon fiber, glass fiber, and ceramics. PEEK materials with higher hardness have better resistance to scratching and abrasion, making them suitable for manufacturi...Read more -
Type Selection Analysis of Hardness Testing Equipment for Large and Heavy Workpieces
As is well-known, each hardness testing method—whether using Brinell, Rockwell, Vickers, or portable Leeb hardness testers—has its own limitations and none is universally applicable. For large, heavy workpieces with irregular geometric dimensions like those shown in the example diagrams below, p...Read more -
Methods and Standards for Hardness Testing of Copper and Copper Alloys
The core mechanical properties of copper and copper alloys are directly reflected by the level of their hardness values, and the mechanical properties of a material determine its strength, wear resistance, and deformation resistance.There are usually the following test methods for detecting the h...Read more -
Selection of Rockwell Hardness Testing for Crankshaft Journals Crankshaft Rockwell Hardness Testers
The crankshaft journals (including main journals and connecting rod journals) are key components for transmitting engine power. In accordance with the requirements of the national standard GB/T 24595-2020, the hardness of the steel bars used for crankshafts must be strictly controlled after quenc...Read more -
Metallographic Sample Preparation Process of Aluminum and Aluminum Alloys and the Metallographic Sample Preparation Equipment

Testing Method for Oxide Film Thickness and Hardness of Automobile Aluminum Alloy Components
The anodic oxide film on automobile aluminum alloy parts acts like a layer of armor on their surface. It forms a dense protective layer on the aluminum alloy surface, enhancing the corrosion resistance of the parts and extending their service life. Meanwhile, the oxide film has high hardness, wh...Read more -
Selection of Test Force in Micro-Vickers Hardness Testing for Metallic Surface Coatings such as Zinc Plating and Chromium Plating
There are many types of metallic coatings. Different coatings require the different test forces in microhardness testing, and test forces cannot be used randomly. Instead, tests should be conducted in accordance with the test force values recommended by standards. Today, we will mainly introduce ...Read more -
