Induction hardening is a method of quickly and selectively hardening the surface of a cylinder piston rod. It is a kind of heat treatment process that can be used to harden the surface of steel shafts without affecting their core. The process involves passing a cylinder shaft through a heating coil into a water quench, which heats, quenches, and hardens the outer skin of the shaft. This process can be used to enhance the mechanical properties in a localized area of a ferrous component.
In industry application, Induction hardening has several benefits including increased wear resistance, increased strength and fatigue life due to the soft core and residual compressive stress at the surface, parts may be tempered after induction hardening to adjust hardness level as desired, deep case with tough core, selective hardening process with no masking required, relatively minimal distortion, and allows use of low cost steels such as 1045.
Benefits of Induction Hardening For Cylinder Piston Rod
1. Increased Wear Resistance
There is a direct correlation between hardness and wear resistance. The wear resistance of a part increases significantly with induction hardening, assuming the initial state of the material was either annealed, or treated to a softer condition.
2. Increased Strength & Fatigue Life due to the Soft Core & Residual Compressive Stress at the Surface
The compressive stress (usually considered a positive attribute) is a result of the hardened structure near the surface occupying slightly more volume than the core and prior structure.
3. Parts may be Tempered after Induction Hardening to Adjust Hardness Level, as desired
As with any process producing a martensitic structure, tempering will lower hardness while decreasing brittleness.
