Start from the failure mode
Abrasion and impact call for Fe-based or Ni60-type deposits; corrosion and oxidation call for IN625, C276-type, or 316L; hot wear calls for cobalt-based alloys.
Laser cladding & hardfacing
Laser cladding powder for wear, corrosion, and repair overlays
Spherical gas-atomized powders for conventional and high-speed laser cladding, laser hardfacing, and DED repair. Nickel self-fluxing, iron-based, cobalt-based, and corrosion-resistant nickel alloys are supplied in cladding-specific particle-size cuts, from trial bags to production tonnage.
Particle-size cuts
- 20–53 µm
- High-speed (extreme high-speed) laser cladding of rods, rolls, and cylinders
- 38–75 µm
- Fine conventional cladding and thin overlays
- 38–105 µm
- General conventional laser cladding
- 53–105 µm
- Conventional cladding with coaxial or lateral feed
- 53–150 µm
- Thick overlays, plasma transferred arc, and heavy repair
Cladding alloy families and typical deposit hardness
| Alloy family | Typical grades | Deposit hardness | Typical uses |
|---|---|---|---|
| Nickel self-fluxing (NiCrBSi) | Ni15, Ni21, Ni31, Ni35, Ni50, Ni60-type | 20–30 HRC (Ni15/Ni21) up to 57–62 HRC (Ni60-type) | Glass molds, cast-iron and copper molds, steel-mill rolls, high-hardness wear coatings |
| Corrosion-resistant nickel alloys | IN625, IN718, C276-type | About 200–230 HV | High-temperature oxidation and corrosion overlays, boiler tubes, marine and chemical equipment, buffer layers |
| Iron-based wear alloys | Fe45, Fe60, Fe31, Fe40 and high-toughness Fe-based types | About 35–64 HRC depending on grade | Hydraulic support columns (chrome-plating replacement), mining picks and tooth shoes, shaft and journal repair, laminar cooling rolls |
| Stainless and tool steels | 316L, 410L, H13, M2 | About 180 HV (316L) to 63 HRC (M2) | Corrosion overlays and transition layers, mold and die repair, high-speed steel cutting and stamping tools |
| Cobalt-based alloys | CoCrW types (Co6, Co12, Co21-type) and Co-X40 | About 32–60 HRC depending on grade | Valve seats, hot wear, corrosion and oxidation service where hot hardness must exceed nickel alloys |
Hardness values are typical deposit ranges from partner datasheets for laser-clad layers. Actual hardness depends on dilution, substrate, laser parameters, layer count, and post-heat treatment; qualify on your own coupons.
How to select the powder
Match the cut to the process
High-speed laser cladding needs a fine 20–53 µm cut with stable flow; conventional heads and PTA tolerate 53–150 µm. Tell us the nozzle type and feeder.
Plan dilution and layers
Deposit chemistry and hardness shift with substrate dilution. A buffer layer (316L, IN625, or a soft Ni grade) often prevents cracking under hard top layers.
Define acceptance
State the required hardness, crack inspection (PT), porosity, thickness, and any salt-spray or wear test so the powder and the deposit can be quoted on the same basis.

Frequently asked questions
What particle size is used for laser cladding powder?
Conventional laser cladding typically uses 45–150 µm cuts such as 53–105 µm or 53–150 µm. High-speed laser cladding uses finer 20–53 µm powder with good flowability so the powder can melt above the substrate.
Which laser cladding powder replaces hard chrome plating?
Iron-based corrosion- and wear-resistant powders, and stainless or nickel-based alloys applied by high-speed laser cladding, are commonly evaluated to replace hard chrome on hydraulic cylinders and rods. The right grade depends on the corrosion test and hardness requirement.
Can I order a small trial quantity?
Yes. Trial bags for process development can be quoted alongside production pricing so you can qualify the powder before ordering by the drum or ton.
