Bremžu sadales vārpstas parasti notiek vairākos virsmas apstrādes procesos, lai uzlabotu to veiktspēju un izturību . Šeit ir dažas izplatītas virsmas apstrādes metodes:
Nitrings
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 sadales vārpsta .
Indukcijas sacietēšana
Indukcijas sacietēšana ir vēl viena plaši izmantota virsmas apstrādes metode . Tas izmanto elektromagnētisko indukciju, lai ātri sildītu sadales vārpstas virsmu un pēc tam to apslāpētu {.} Rūdīts virsmas slānis ar augstu cietību un labu nodiluma izturību, savukārt korpusa kodols paliek salīdzinoši mīksts un grūts, nodrošinot labas vispārējas īpašības {{2 2}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}.
Galvanizācija
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 Aizsardzība .
Šāviens
Shot peening is a process that bombards the surface of the camshaft with small shot particles. This induces compressive stresses on the surface, which helps to improve the fatigue resistance of the camshaft. By increasing the surface compressive stress, the camshaft is more resistant to cracking and deformation under cyclic loading.
