Description

The CrNi layer offers very good wear protection in combination with high corrosion protection. Here, all the advantages of hard chrome and electroless nickel are being combined in one coating system. This combination layer meets the highest demands and is ideally suited for the use in an environment with high chemical and mechanical stress. The CrNi layer system In hybrid coating, components are first electroless nickel-plated and then hard chrome-plated. The combination layer guarantees very good wear protection in conjunction with strong corrosion protection and high chemical resistance. Due to its functional properties, the hybrid coating is ideally suited for use in an environment with high chemical and/or mechanical stress. The layer thicknesses are based on the technical requirements, e.g. 0.030 mm electroless nickel and 0.040 mm hard chrome. To improve the coating adhesion, we recommend a heat treatment of the components as an intermediate step after electroless nickel plating. The components are tempered in a furnace between 230°C – 400°C. The thermal post-treatment increases the adhesion of the electroless nickel layer. Tempering also increases the hardness of the electroless nickel layer to about 1000 (± 50) HV and improves the wear behavior. Coating properties In hybrid coating, the electroless nickel layer provides corrosion protection that is closed on all sides and the hard chrome layer ensures high hardness without distorting the material. The low coefficient of friction confirms the anti-adhesive properties of the chrome layer. This describes the behavior of chrome surfaces to repel aqueous media and dirt.
