(1) Improve surface hardness and wear resistance: Ion nitriding significantly improves the surface hardness and wear resistance of moulds by forming a nitriding layer on the surface of the moulds, thus prolonging the service life of the moulds;
(2) Enhance fatigue strength and corrosion resistance: the nitriding layer not only improves the hardness of the mould, but also enhances its fatigue strength and corrosion resistance, which further protects the mould from damage;
(3) Control the organisational structure of nitriding layer: by adjusting the ratio of nitrogen, hydrogen and other gases, the phase composition of the compound layer can be freely adjusted to obtain the expected mechanical properties;
(4) Applicable to a variety of materials: ion nitriding is applicable to a variety of materials, including steel and other metals, improving its applicability and flexibility;
(5) Small deformation: due to the treatment at low temperature, the deformation of the treated workpiece is extremely small, and there is no need for further processing after treatment, which is extremely suitable for the treatment of finished products;
(6) Easy to achieve local nitriding and uniform nitriding: ion nitriding is easy to achieve local nitriding and uniform nitriding, and the area and degree of nitriding can be precisely controlled according to the needs;
(7) Light pollution to the environment: Ion nitriding is carried out in a vacuum, which does not produce harmful emissions and causes less pollution to the environment, while the labour conditions are also improved.
