Bromskamaxlar genomgår vanligtvis flera ytbehandlingsprocesser för att förbättra deras prestanda och hållbarhet . Här är några vanliga ytbehandlingsmetoder:
Nitrering
Nitriding is a process that introduces nitrogen atoms into the surface of the camshaft. This forms a hard nitride layer, which improves the wear resistance, fatigue strength, and corrosion resistance of the camshaft. The nitrided surface has a high hardness, reducing the friction between the camshaft and other components, thus prolonging the service life of the kamaxel .
Induktionshärdning
Induction hardening is another widely used surface treatment method. It uses electromagnetic induction to heat the surface of the camshaft rapidly and then quenches it. This process results in a hardened surface layer with high hardness and good wear resistance, while the core of the camshaft remains relatively soft and tough, ensuring good overall mechanical properties.
Galvanisering
Electroplating, such as chrome plating, is often employed. A layer of chromium is plated onto the surface of the camshaft. Chrome plating can improve the surface smoothness, reduce friction, and enhance the corrosion resistance of the camshaft. It also gives the camshaft a shiny appearance, which is beneficial for both aesthetics and skydd .
Skjutning
Shot Peening är en process som bombarderar ytan på kamaxeln med små skottpartiklar . Detta inducerar kompressiva spänningar på ytan, vilket hjälper till att förbättra trötthetsresistensen hos kamaxeln . genom att öka ytkompressivt stress, kamaxeln är mer motståndskraftig mot sprickor och deformering under cyklicy {{}}}}}}}}}
