Hydraulic cylinders often fail due to wear and corrosion—especially in harsh industrial environments.
Laser cladding replaces traditional hard chrome plating with stronger, safer, and longer-lasting alloy coatings that withstand pressure, friction, and corrosion.
Hard chrome has served industry for decades, but environmental regulations and performance limits are pushing manufacturers to find better solutions. Laser cladding offers a proven, eco-friendly upgrade for both new hydraulic parts and remanufacturing. Here’s why it matters.
Why is laser cladding a better alternative to hard chrome?
Hard chrome cracks, peels, and contaminates. Laser cladding1 bonds permanently with the substrate.
Laser cladding1 forms a metallurgically bonded alloy layer that resists wear and corrosion—without the environmental risks of chrome.
What’s wrong with hard chrome plating2?
Hard chrome plating is widely used for hydraulic cylinder rods and surfaces, but it’s becoming outdated. It suffers from microcracking, delamination, and a hazardous chemical process that involves hexavalent chromium. Regulatory pressure is growing worldwide to phase it out.
In contrast, laser cladding uses a high-power laser to fuse metal powders (such as Inconel, Stellite, or tungsten carbides) directly onto the rod surface. This process creates a dense, crack-free, wear-resistant layer that lasts significantly longer than chrome—without the toxic chemicals.
| Criteria | Hard Chrome Plating | Laser Cladding |
|---|---|---|
| Bonding | Mechanical | Metallurgical |
| Wear Resistance | Moderate | High |
| Corrosion Resistance | Limited | Excellent |
| Environmental Impact | High (toxic waste) | Low (no toxic residue) |
| Service Life | Shorter | Longer |
What this means for maintenance teams
Instead of replacing or replating worn rods every few months, laser-cladded rods can last significantly longer—even under extreme mechanical load, heat, and chemical exposure. This reduces downtime, extends maintenance cycles, and lowers overall cost of ownership.
What are the benefits of laser cladding3 for hydraulic systems?
From mining and oil rigs to injection molding and marine equipment—hydraulic cylinders work in demanding environments.
Laser cladding is the most robust surface treatment for hydraulic parts, delivering high performance and sustainability.
Key benefits that outperform traditional chrome
1. Metallurgical bonding, no peeling
Unlike electroplated chrome, which relies on weak mechanical adhesion, laser cladding3 fuses the coating to the base metal at the molecular level. This eliminates delamination, cracking, or peeling even under repeated stress and impact.
2. Environmentally compliant
Laser cladding avoids hexavalent chromium, making it fully compliant with EU REACH and other international environmental standards. Companies using laser cladding3 reduce their toxic emissions, waste treatment costs, and environmental liabilities.
3. Works for new parts and remanufacturing
Laser cladding is highly versatile. It can be applied to new hydraulic components or used to restore worn or damaged parts—saving money and reducing raw material consumption.
| Feature | Benefit |
|---|---|
| Crack-free alloy coatings | High resistance to fatigue and stress |
| Customizable cladding alloys | Tailored for specific load or corrosion |
| Low heat input | Minimal distortion or dimensional shift |
| Compatible with polishing | Achieve mirror-smooth surfaces |
| Long-term durability | Lower TCO for heavy-duty hydraulic systems |
