This document specifies the technical requirements and testing methods for metallic laser cladding coatings.
This document provides pre-treatment, coating materials, preparation processes, and post-treatment related to coating preparation. It also presents the technical requirements and testing methods for the appearance, thickness, hardness, microstructure, and surface defects of metallic laser cladding coatings, as well as the testing methods for the wear resistance and corrosion resistance of coatings.
Laser cladding is a non-equilibrium dynamic process that utilizes a high-energy laser beam to melt and condense with a thin layer of the substrate surface, forming a metallurgically bonded additive layer, which is widely used in industrial manufacturing fields such as energy, aviation and mining due to its strong adhesion, environmental friendliness, substantial coating thickness, and good material compatibility. Especially in heavy load working conditions and environmentally sensitive fields, laser cladding coatings have significant advantages. At present, laser cladding has achieved a global market size of US$600 million annually, and is growing at a rate of 10% per year. However, the absence of ISO standards for metallic laser cladding coatings has led to uncertainties in technical requirements, testing protocols, and quality assessment methods, thereby limiting industrial adoption and academic collaboration. Developing ISO standards for metallic laser cladding coatings not only helps to standardize existing laser cladding technology but also promotes technological innovation and industrial upgrading. Unified standards can promote technological communication and cooperation between different countries and regions, and drive the development of laser cladding technology. Therefore, it is urgent and necessary to establish technical requirements and testing standards for metallic laser cladding coatings.
This document aims to establish the technical requirements and testing for metallic laser cladding coatings, providing a unified technical framework for researchers in both industry and academia worldwide, ensuring consistent and high-quality metallic laser cladding coatings, and promoting the application of laser cladding technology
