The picture above shows an operator at a touch screen that will precisely place the workpiece under the laser beam using a 5-axis controller. The laser itself is a PRC-2.2 KW CO2 laser with both continuous and pulse modes.
Laser Cladding Attributes
- Relies on the improved
properties displayed by the cladding material.
- Increased Wear Resistance
- Increased Hardness
- Improved Corrosion Resistance
- Powders are typically utilized because of their relatively high absorption.
- Results in extremely small dilution of the base metal.
- Capability of relatively high deposition rates while imparting low heat input to the base metal.
- Easily controlled process variables.
Laser deposition processes are beginning to gain widespread acceptance for repair, refurbishment, and rapid prototyping. The laser deposition process typically involves the use of powder that is efficiently melted by the laser beam and precisely deposited onto the substrate material. Characteristics of laser deposition processes include low thermal distortion and minimal metallurgical degradation to the substrate, as well as relatively high deposition rates and rapid solidification rates associated with the deposit. This combination of attributes makes the process an ideal candidate for selectively producing engineered microstructures for a wide variety of applications.
Through research and development Laserclad is now able to offer a proprietary material with included Tungsten carbide particles for hard facing wear surfaces, this material outperforms chromium and is more economical than bolted-in carbide. The ability to selectively place the hard surfacing material without masking the substrate is a definite advantage. The cladding material is metallurgically bonded with the substrate and is a quality improvement over plating.
With a laser beam it is possible to inject an enhancing alloy powder into the surface of a substrate to obtain critical quality characteristics such as, corrosion resistance, increased hardness, and improved fatigue life. This process has proven itself for economy and quality. Our engineers would be pleased to discuss and/or test your requirements.
Laser Surface Transformation
The laser beam‘s ability to heat treat a defined area on an object part is superior to flame or induction heat treatment; because of the limited heat affected zone (HAZ) experienced on the full object part. This is a critical element when the defined heat treat area is near a necessary annealed area.
Laser Surface Remelting (Rapid Solidification)
A relatively new process in surface modification technology is surface remelting. The surface of certain alloys when remelted and quickly quenched (solidified) exhibits improved performance characteristics. The remelted surface may also exhibit improved surface smoothness.
The flexibility and controllability of laser surface technology should be an important consideration in production of your current products, or in the design of new products. Laserclad is ready to sample and service your prototyping or production requirements.
