Laser Cladding Powder for Industrial Repair and Surface Protection

JINGYE is a laser cladding powder supplier manufacturing iron-based, nickel-based and cobalt-based alloy powders for component repair, dimensional restoration and surface protection. Our powders are used in mining machinery, coal equipment, metallurgy, petroleum, chemical processing, mold repair and general industrial maintenance.

JINGYE metal powder for laser cladding is available in different alloy compositions, particle size ranges and deposited hardness levels. Standard and customized powders can be matched to the substrate, powder feeding system, laser process and required resistance to wear, corrosion, oxidation or elevated temperatures.

• ♦  Powder families: iron-based, nickel-based and cobalt-based alloys
• ♦  Available processes: conventional laser cladding, high-speed laser cladding, laser metal deposition and selected PTA or spray applications
• ♦  Controllable properties: alloy composition, particle size, morphology, flowability and deposited hardness
• ♦  Supply options: standard grades, application-specific particle cuts and customized alloy development

JINGYE Laser Cladding Powder Products

The following grades and particle sizes are based on JINGYE's documented production range. Final specifications and inspection items are confirmed according to the agreed technical data sheet.

Alternative particle size distributions can be discussed according to the powder feeder, laser cladding head, deposition rate and target layer thickness.

Iron-, Nickel- and Cobalt-Based Cladding Alloy Powders

These hardness values are reference ranges from JINGYE product documentation. Actual coating hardness and performance also depend on substrate composition, dilution, heat input, layer thickness, cooling conditions and subsequent machining or heat treatment.

Iron Metal Powder for Laser Cladding

JINGYE iron-based products are pre-alloyed metal powders for laser cladding, rather than general-purpose pure iron metal powder. Elements such as chromium, nickel, molybdenum, carbon, silicon and boron are controlled to obtain the required deposition behavior, hardness, corrosion resistance and machinability.

Iron-based powders are commonly selected for hydraulic supports, rollers, shafts, gears and other large steel components where repair cost, machinability and coating performance must be balanced. Stainless steel grades such as 304, 316L and 17-4PH are also available for corrosion-resistant cladding and surface restoration.

How to Select Metal Powder for Laser Cladding

Powder selection starts with the base material, service environment, failure mechanism and required condition of the finished cladding layer.

• ♦  Substrate compatibility: Match the alloy system to the steel, stainless steel, nickel alloy or other base material to control bonding and cracking risk.
• ♦  Primary failure mechanism: Identify whether the component is affected by abrasion, corrosion, oxidation, impact, galling, heat or dimensional wear.
• ♦  Target hardness and machinability: Higher hardness improves resistance to some forms of wear but can increase machining difficulty and sensitivity to cracking.
• ♦  Powder feeding system: Particle size and flowability must match the feeder, nozzle and deposition rate of the laser equipment.
• ♦  Cladding process: Conventional laser cladding, high-speed cladding, LMD, DED and PTA can require different particle cuts and process characteristics.
• ♦  Layer requirements: Coating thickness, allowable dilution, surface finish and machining allowance influence both the powder and process window.

Powder Manufacturing and Quality Control

As an integrated laser cladding powder supplier, JINGYE controls powder production from alloy preparation through atomization, classification, inspection and packaging. The manufacturing route is selected according to the alloy family, target particle morphology and application requirements.

1. Alloy preparation: Raw materials and alloy composition are prepared according to the specified grade.

2. Melting and atomization: Gas atomization or water-gas combined atomization is selected according to the required powder characteristics.

3. Classification and screening: Powder is separated into the required particle size range and screened to control oversize particles.

4. Powder inspection: Available inspections include chemical composition, particle size distribution, morphology, oxygen and nitrogen, Hall flow, apparent density and tap density.

5. Batch identification: Production and inspection records support batch traceability and repeat-order consistency.

The documented laser cladding alloy series has controllable particle size and a documented sphericity value of at least 0.90. Final inspection limits are defined in the agreed product specification, and an inspection report or certificate of analysis can be supplied as required.
