Hello everyone, this article mainly discusses the application of ED-XRF in coating testing within the fastener industry.

Fasteners refer to a type of mechanical components used to securely connect two or more parts into a unified whole. They are widely applied in various mechanical equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters, and other products. Their characteristics lie in their diverse types, specific specifications, versatile performance, high standardization, deep serialization, and strong universality.

Common types of fasteners include bolts, screws, nuts, washers, and others. Common surface treatment methods for fasteners include galvanization, zinc-nickel plating, and DACROMET. DACROMET is a novel type of anti-corrosion coating primarily composed of zinc powder, aluminum powder, chromic acid, and deionized water. As it contains aluminum elements that cannot be detected in the atmospheric state, the aluminum content directly influences the coating thickness.

Given the various sizes and types of fasteners such as bolts and screws, as well as the substantial testing volume, there is a need for instruments that can accommodate different sample sizes and meet the requirements for rapid and efficient testing.

Our XD-1000(ED-XRF) overhead-type structural instrument is an ideal solution that caters to various demands for coating and composition testing in the fastener industry. It can customize testing molds according to specific customer needs, easily handle various sample specifications, and effectively meet the high-volume sample testing requirements. As a result, it has gained widespread recognition in the production inspection of the fastener industry.
