In heavy industries where performance and longevity are non-negotiable, hard chrome finishing plays a vital role. This process enhances the durability, corrosion resistance, and wear performance of critical metal components — ensuring reliability in even the harshest environments.
At Gaja Engineering, our hard chrome finishing services are trusted across Australia’s toughest sectors — from hydraulics and mining to agriculture and aerospace — to restore, protect, and extend the life of precision-engineered parts.
Hydraulics: Extending Cylinder Life
In hydraulic systems, precision and surface integrity determine system performance. Hard chrome finishing provides an ultra-smooth, wear-resistant layer to hydraulic rods, pistons, and shafts, reducing friction and preventing pitting or scoring. This significantly extends service life and ensures smooth operation under high pressure.
Mining: Built for Harsh Conditions
Mining equipment faces extreme wear from abrasive materials and constant exposure to moisture. Hard chrome coatings form a protective barrier against corrosion and impact, ideal for shafts, rollers, and drill components. Gaja Engineering’s advanced surface finishing solutions help mining operations reduce downtime and maintenance costs.
Agriculture: Protecting Productivity
Agricultural machinery often operates in dusty, abrasive, and corrosive conditions. Applying industrial hard chrome on parts like axles, hydraulic cylinders, and plunger rods provides superior resistance to rust and wear —keeping farm equipment in peak working condition for longer.
Aerospace: Precision Meets Performance
In aerospace, precision, and reliability are critical. Hard chrome finishing delivers tight tolerances and exceptional surface quality for landing gear, actuators, and engine components. The coating’s hardness and low friction reduce wear, ensuring safe, long-term operation in demanding environments
Other Applications: Beyond Heavy Industry
Hard chrome finishing is also used in marine, defense, transport, and manufacturing sectors —anywhere metal parts require enhanced performance and protection. Whether for refurbishment or OEM components, Gaja Engineering provides custom chrome plating and surface restoration with industry-grade accuracy.
