Iron-Based Laser Cladding Powders

Iron-based alloy powders provide an economical solution for wear-resistant coatings, corrosion protection and dimensional restoration of steel components.

GREENSTONE iron-based powder systems cover low- to high-hardness formulations and stainless-steel-based alloys. Depending on composition, deposited layers can provide approximately 20–65 HRC hardness.

Typical applications include hydraulic rods, piston rods, shafts, bearing positions, rollers, mining components, oil drilling components, valves, molds and general machinery repair.

Standard internationally recognized materials such as 316L and 410L stainless steel powders are also available for applications requiring corrosion resistance, dimensional restoration or stainless-steel surface modification.

Nickel-Based Laser Cladding Powders

Nickel-based powders are designed for applications requiring a combination of corrosion resistance, wear resistance, oxidation resistance and elevated-temperature performance.

Different alloy formulations provide a broad hardness range, from relatively ductile corrosion-resistant deposits to approximately 60–65 HRC high-hardness wear-resistant coatings.

They are particularly suitable for oil & gas components, valves, pumps, chemical-processing equipment, marine components, molds, shafts and high-value industrial parts.

Nickel-based powders generally provide good wettability and metallurgical bonding during laser cladding while maintaining excellent resistance to aggressive industrial environments.

Cobalt-Based Laser Cladding Powders

Cobalt-based laser cladding powders are intended for severe service conditions requiring hot hardness, wear resistance, corrosion resistance, galling resistance and thermal stability.

Co-Cr-W and Co-Cr-Mo alloy systems can be selected according to operating temperature, impact conditions and wear mechanisms.

Typical applications include valve seats, valve sealing surfaces, pump components, cutting and forming tools, high-temperature wear parts and heavy-duty industrial components.

Nickel Superalloy Powders

GREENSTONE supplies internationally recognized nickel superalloys for demanding repair and additive manufacturing applications.

Available materials include Inconel 625, Inconel 718, Hastelloy C22 and Hastelloy C276, among other application-specific alloys.

These materials provide excellent combinations of high-temperature strength, oxidation resistance, corrosion resistance and mechanical stability, making them suitable for the energy, petrochemical, marine, chemical-processing and high-temperature machinery industries.

They can be used for laser cladding, component repair, feature addition and suitable DED additive manufacturing applications.

Copper-Based Laser Cladding Powders

Copper and copper-alloy powders provide combinations of thermal conductivity, electrical conductivity, corrosion resistance, anti-friction performance and metallurgical functionality.

Typical materials include aluminum bronze and tin-bronze-based alloy systems such as CuAl10Fe1 and CuSn12Ni2.

Applications include bearings, bushings, sliding surfaces, marine components, conductive components and functional copper-alloy coatings.

Key Advantages

Excellent Metallurgical Bonding
Laser cladding creates a metallurgically bonded layer between the deposited alloy and substrate, providing substantially different interface characteristics from mechanically bonded coating processes.

Broad Hardness Range
Powder compositions can be selected from relatively ductile restoration alloys through high-hardness wear-resistant alloys approaching approximately 65 HRC, depending on material and processing conditions.

High Wear Resistance
Special iron-, nickel- and cobalt-based systems provide protection against abrasive, adhesive and sliding wear.

Excellent Corrosion Resistance
316L, nickel alloys, Inconel, Hastelloy and selected cobalt alloys are available for corrosive and chemically aggressive environments.

High-Temperature Performance
Nickel superalloys and cobalt alloys maintain useful mechanical and surface properties under elevated-temperature operating conditions.

Controlled Dilution
Optimized laser processing enables controlled heat input and relatively low substrate dilution while maintaining metallurgical bonding.

Stable Powder Feeding
Controlled powder morphology and particle-size distribution support consistent feeding through coaxial and lateral powder feeding systems.

Suitable for Repair and New Manufacturing
The same powder portfolio can support laser cladding, LMD, DED, industrial remanufacturing, surface functionalization and additive feature manufacturing.

Customized Powder Solutions
Chemical composition, particle-size distribution and performance targets can be optimized according to substrate, service conditions and laser processing requirements.
