Why Hydraulic Support Rods Need Surface Treatment
Hydraulic support rods play a critical role in automotive applications, providing reliable support for hoods, trunks, and liftgates. These components must maintain consistent performance despite exposure to the elements and repeated use over time. For decades, chrome and nickel plating have been used to protect these rods. However, these traditional methods present limitations, such as chipping, flaking, and compromised corrosion resistance as the plating wears.
UltraOx®, Advanced Heat Treat Corp.’s (AHT) proprietary ferritic nitrocarburizing and oxidation process, offers a more durable and effective solution. By diffusing hardened layers directly into the steel substrate, UltraOx® enhances wear resistance, toughness, and corrosion protection—without the downsides of plated coatings.
Key Advantages of UltraOx® Over Chrome and Nickel Plating:
Enhanced Durability
Chrome and nickel plating can be prone to cracking, peeling, and delamination under stress. UltraOx® overcomes this by diffusing nitrogen and carbon into the steel, forming a tough, scratch-resistant surface. This durability ensures hydraulic rods withstand the rigors of repeated use, maintaining structural integrity over time.
Superior Corrosion Resistance
Hydraulic rods operate in punishing environments, from road salt and moisture to extreme temperature swings. UltraOx® delivers exceptional corrosion protection through its multi-layered surface, which includes a nitride base, protective oxide layer and proprietary sealant.
Enhanced Toughness and Wear Resistance
Plated coatings often degrade, separating from the base material and compromising functionality. UltraOx® eliminates this risk with its nitrided layers, which provide outstanding wear resistance. The process creates a surface that resists abrasion and maintains consistent performance, extending the lifespan of hydraulic rods.
Functional and Aesthetic Excellence
UltraOx® imparts a black oxide finish that not only enhances the visual appeal of hydraulic rods but also delivers practical benefits. The low-friction surface reduces wear during operation, while its scratch-resistant properties ensure a polished appearance throughout time. This combination of form and function makes UltraOx® an ideal choice for manufacturers seeking both reliability and a visually appealing look.
Environmentally-Friendly
UltraOx occurs within a controlled atmosphere and does not use carcinogenic chemicals like chrome plating (hexavalent chromium). UltraOx produces minimal waste/air emissions.
Why Choose UltraOx®?
By adopting UltraOx® for hydraulic support rods, manufacturers unlock several benefits such as increased wear resistance, extended part life, and reduced maintenance costs. UltraOx® offers a long-lasting solution that performs consistently under demanding conditions. This innovative treatment enables automotive components to meet the rigorous standards of modern engineering, delivering unmatched value to manufacturers and end-users alike.
Choose UltraOx®—where durability, corrosion resistance, and performance converge to redefine excellence in hydraulic rod applications.
