磨损 & 磨损测试

When friction is the predominant factor causing deterioration of your materials, abrasion and wear testing provides data to compare materials or coatings and can help you predict the lifetime of your product.

磨损 & Wear testing evaluates resistance of materials and coatings to deterioration

磨损 testing is used to test the abrasive resistance of solid materials. 金属等材料, 复合材料, 陶瓷, and thick (weld overlays and thermal spray) coatings can be tested with these methods. The intent of abrasion testing is to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.

We offer various abrasion and wear test methods, and can assist in choosing the best method for your project. Our engaged experts work diligently to help make certain your materials are safe, 质量, 顺从的，符合目的的. 

磨损试验方法:

销磨损, rubber wheel abrasion, taber abrasion, falling sand abrasion & RCA磨损

im体育APP’s material testing engineers perform fast, repeatable testing to help you predictively rank your materials in a similar relative order of merit as would occur in an abrasive environment.  

• 销磨损 (ASTM G132) is performed using two pin specimens; the subject material and a reference material. A pin is positioned perpendicular to an abrasive surface, which is mounted on and supported by a flat surface. The pin abrasion testing machine permits relative motion between the abrasive surface and the pin surface. 
• 橡胶轮磨损 (ASTM G65) is performed by loading a rectangular test sample against a rotating rubber wheel and depositing sand of controlled grit size, 作文, 以及它们之间的流速. 
• 泰伯磨损 (ASTM D1044, ASTM D4060, and others) is performed by mounting a flat specimen, 正方形或圆形, to a turntable platform that rotates two abrasive wheels over the specimen at a fixed speed and pressure.  
• 落砂磨损 (ASTM D968) is used to determine the resistance of organic coatings to falling sand. The coatings are typically applied to a plane rigid surface, like glass or metal, before testing. 
• RCA磨损 (ASTM F2357) is performed using a Norman Tool Machine. Inks and coatings on printed membrane switches are affected by repeated abrasive forces, 最常见的是人的手指. Other conditions that contribute to visible wear include cleaning, 擦拭, 摩擦, 航运, 存储, 以及意外损害.

医疗器械磨损 & pin-on-disk穿

A customized wear testing program can be configured to closely mimic actual operating conditions, 包括温度和液体, 和磨损方向. im体育APP’s state-of the art laboratories and equipment deliver wear testing data that is much more relatable to the specific work environment in question.

• 医疗器械磨损 is utilized to characterize the tribological properties of a medical device by simulating the kinematics and kinetics of the human body, in an environment that closely simulates intended use. Commonly tested devices include hip, knee, and spinal devices. 
• Pin-on-disk穿 (ASTM可以, ASTM G133, and ASTM F732) involves abrading two materials – one material is machined into a pin, the other into a disk – to determine a variety of properties, including wear rates and frictional force coefficients. Pin-on-disk can be conducted at elevated temperatures or in submerged environments to more accurately simulate “real life” wear conditions.
