Wear Resistant Coating on Metal

Low weight to strength metals is integral part of aerospace automotive & transportation and many other industries. Offering the possibility of weight reduction and cost-efficient performance, they can contribute to the increased efficiency, performance and sustainable manufacture in these industries.

Despite their favorable strength-to-weight ratios, lightweight metals tend to have low hardness and exhibit poor resistance to mechanical wear.

Wear-resistant coatings protect against wear and tear caused by friction, impact, mechanical stress, corrosion, and other forces.

The coating is a critical step that permits any tool to withstand wear. Coatings help the cutting tool evacuate chips from the flutes quicker, removing the HOT chips from the ground surface. In the last ten years, the development of more heat and wear-resistant coatings has boosted tool durability and productivity.

High surface hardness, excellent wear resistance, steady chemical performance, heat and oxidation resistance, a small friction coefficient, and low thermal conductivity are properties of coated tools. Compared to uncoated tools, cutting life may be enhanced three to five times with coated tools. In addition, the speed is increased by 20 to 70 percent, the machining precision is improved by 0.5 to 1 level, and the tool consumption cost is decreased by 20 to 50 percent.

The performance of the cutting tool has a significant effect on cutting efficiency, precision, and surface quality. Unfortunately, there are perpetual inconsistencies between tool, two primary performance metrics, hardness and strength. Materials with a high hardness have poor power, and a reduction in hardness is typically required to boost strength.

To resolve this contradiction in carbide materials and increase the cutting performance of tools, it is more effective to coat one or more layers of hardness, high wear resistance material which is possible with Laser Cladding System since you can vary the thickness of the coatings from few 100 micron’s to mm’s.
