Laser Hardening Is The Future Of Heat Treating.
What is Laser hardening?
Laser hardening is an ideal method for treating highly strained, complicated components. This is owing to tailored heat input that is limited to certain locations, which almost eliminates component warping during processing.
Heating and cooling occur so quickly that no external quenching is necessary. Laser hardening is commonly used to cut edges, sharp corners, pockets, and other significant geometrical characteristics.
Benefits of Laser Hardening
Less Reworking
Due to the minimal heat input, the cost of reworking is decreased or eliminated totally.
No Distortion
While traditional hardening techniques cause deformation owing to increased energy input and subsequent quenching, laser hardening preserves the component's original condition.
Precise Control
The laser technology and temperature control allow for exact control of the heat input.
Hardening Small And Delicate Components
In comparison to other methods, the laser allows for accurate hardening of even locally constrained functional surfaces.
Fast Throughput Time And High Productivity
The laser's non-contact and distortion-free processing enhances throughput time while reducing the need for preparation and reworking.
Completely Independent Of The Geometry
Scanning technology allows for rapid "on the fly" changes to component hardness geometry. This implies that no conversion of the optics or full system is required.
How Does The Laser Hardening Process Work?
- Laser hardening involves heating the skin of a carbon-containing workpiece composed of steel or cast iron to just below the melting point, which is typically between 900 and 1400 degrees Celsius. Approximately 40% of irradiation electricity is absorbed.
- When the nominal temperature is attained, the laser beam begins to travel, gradually heating the surface in the direction of feed.
- As the laser beam advances, the surrounding material rapidly cools the heated surface, a process known as self-quenching.
- The outer layer’s hardening depth is typically 0.1 to 1.5 millimeters, while it can be 2.5 millimeters or more in some materials.
Application of Laser Hardening
Surface hardening
Laser hardening is similar to surface hardening methods. Ultra-stressed portions of steel or cast iron components are often hardened just locally, such as in tool production for automobile body building.
Hardening camshafts
Camshafts are components found in combustion engines. Their complicated shape, required for switching control times or partial cylinder deactivation, as well as their intense material stress utilization scenario, necessitate precise and selective hardening.
Contract hardening
Contract manufacturing and metal processing firms rely on hardening process orders because it is not economically viable to purchase their own hardening equipment for a variety of reasons.
