Laser heat treatment

Achieve precise case depth and limited distortion, without compromising on part/tool performance and quality. The process is inherently a LEAN (single piece flow) process with high processing speed, precision heating control, as well as being highly flexible, easily handling most work piece shapes and geometries.

Industrial applications

  • Carbon alloy steels and cast irons
  • Bearing surfaces
  • Cutting surfaces
  • Pumps
  • Valve seat and seal surfaces
  • Drive train components
  • Gears, pulleys and cams
  • Hand tools, needles and pins
  • Forming tools
  • Stamping dies
  • Turbine blades
  • Powder metal parts

Laser heat treatment benefits

Transform your components with laser heat treatment that delivers measurable performance improvements. Our advanced process enhances durability while maintaining exact specifications.

  • Selective hardening both is depth and location
  • Low or negligible distortion
  • No post processing is required
  • Highly directional heating via line of site heat treating
  • Process speeds typically 3x faster than induction methods
  • Environmentally friendly dry process requiring no quench oil or fluids
  • Does not require absorbent coatings
  • Process very forgiving with respect to surface contaminants
  • Higher hardness achievable — over HRC 60 without cracking
  • Fatigue life improvement for powder metal parts and drive train components

Transform surface performance

APEX ETG’s laser heat treatment service transforms your critical components through precision surface hardening. Our high-power diode laser technology creates hardened surfaces with precise case depths. The localised heating process ensures negligible distortion, eliminating costly post-processing while delivering enhanced wear, fatigue, and corrosion resistance. With processing speeds up to three times faster than traditional methods, we help you reduce production time and costs while improving component performance.

FAQ section

How much can laser cladding extend component life?

Laser cladding can significantly extend component service life by up to 100% when compared to standard parts performance.

This dramatic improvement comes from the mechanical properties of high-performance alloys applied to the surface and from the metallurgically bonded protective coating, keeping your critical equipment operational longer.

What productivity improvements does laser cladding offer?

High-speed laser cladding (HSLC) delivers productivity gains of up to 300% over traditional coating methods. The combination of faster scanning speeds and minimal post-processing requirements means your components are back in service sooner with better performance.

How does laser cladding reduce operational downtime?

Our laser cladding turnaround time average over the last 3 years is 10 working days. Depending on the component overall dimensions and weight our team will collaborate with you to design an efficient repair process.

Can laser cladding help optimise component weight?

Targeted material deposition through laser cladding achieves 10-20% weight reduction in aerospace and automotive applications. This precision approach eliminates bulky protective coatings while maintaining superior protection, improving both energy efficiency and overall performance.

What mechanical properties of components can be optimised by using laser cladding?

Laser cladding can help optimise the following mechanical properties:
Hardness, Wear Resistance, Corrosion Resistance, Fatigue Strength, Toughness, Thermal Stability and Bond Strength.
