dc.description.abstract The manufacturing industry continually seeks innovative methods to enhance the mechanical properties, wear resistance, and overall performance of materials used in critical applications, such as in the production of molds, dies, and machine components. This study explores the application of laser heat treatment and surface coating techniques to improve the properties of hot X40CrMoV5-1 steel, commonly used in the production of tooling and machinery for Metalworking and Steel Casting (MSC) industries. Laser heat treatment, a precise and localized heat treatment process, is employed to modify the microstructure of X40CrMoV5-1 steel, enhancing its hardness, toughness, and fatigue resistance. This study investigates various laser parameters, such as power, scanning speed, and beam type, to optimize the heat treatment process for achieving the desired material properties. Through microstructural analysis and hardness testing, the effects of laser heat treatment on the steel's mechanical properties are assessed. In addition to laser heat treatment, surface coatings are applied to further enhance the performance of X40CrMoV5-1 steel. Various coating materials, such as nitrides, carbides, and diamond-like carbon (DLC), are considered to improve the steel's wear resistance, corrosion resistance, and reduced friction coefficient. For this research Tungsten carbide was applied for coating the surface. The adhesion and performance of these coatings are evaluated through scratch tests, tribological studies, and corrosion resistance assessments. And Tungsten carbide was applied for coating the surface. The results of this research contribute to the development of advanced materials and processing techniques for the MSC industry, ultimately leading to improved tool life, reduced downtime, and increased productivity. The combination of laser heat treatment and surface coatings offers a promising approach to enhance the performance and longevity of X40CrMoV5-1 steel components, meeting the stringent demands of the Metalworking and Steel Casting industry. en_US
