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.
