ZINC-NICKEL PLATING

2024-07-25

Both Zinc and Nickel are widely used in a variety of finishing applications on their own, but a combination of the two metals provides a far greater resistance to corrosion than the individual metals can offer.

Deposits of this metal plating offer a durable finish that helps reduce the development of metal frays that can cause damage to the finished piece. Zinc Nickel provides excellent adhesion with smooth deposits that are blister free.

Top coats and passivation treatments can also improve long-term performance. Zinc Nickel plating can also serve as a “sacrificial” coating for an underlying substrate — corroding before the metal underneath is effected. During salt spray testing, zinc nickel coated parts can withstand the formation of white rust for up to 500 hours, and up to 1,000 hours for red rust.

Zinc Nickel coating is also preferred in applications where the part or component is in contact with aluminum. It helps drastically reduce corrosion and is also able to withstand the higher temperatures associated with engines in automotive industry.

Zinc nickel is the perfect alternative to conventional zinc for any steel part that is intended for exterior use. Zinc nickel provides the most economical corrosion protection available today.

Benefits of Zinc Nickel Plating:

WEEE, ROHS and EVL compliant trivalent passivation (Chrome 6 Free)
High thermal resistance (up to 200˚C) makes it suitable for high temperature automotive applications
Provides Superior Corrosion Resistance – protects the base metal for over 1000 hours to red rust
Around four times the hardness and therefore wear resistance of standard Zinc plating
Many of these features make Zinc-Nickel and environmentally friendly alternative for Cadmium plating
Offers great adhesion for post processing operations

The car chassis includes four major systems, including transmission system, driving system, steering system, and braking system.

Transmission system

It is an important part of the automotive chassis, which includes the clutch, transmission, transmission shaft, drive axle, etc..The function is to transfer the power output from the engine to the driving wheels, allowing them to rotate.

Driving system

It includes components such as wheels, tires, suspension system, and frame. The function is to bear the weight of the car, receive the power brought by the transmission system, and drive the car. Furthermore, there is a buffer for external impacts and vibrations received by the vehicle body.

Steering system

The steering system includes the steering wheel, steering gear, steering knuckles and power steering system. Its main function is to control the direction of the vehicle, achieving steering and operation.

Braking system

The function of the braking system is to stop the car and ensure the safety of the driver.It includes two independent braking systems, namely the driving brake and the parking brake. It applies braking force to the wheels through the coordination of components such as brakes, brake pipelines, and brake control systems, achieving vehicle deceleration and parking. At the same time, the braking system can also improve the braking performance and safety of the vehicle through the Anti-lock Braking System (ABS)

In summary, the chassis carries the weight of the vehicle and provides stable driving and operation.Due to long-term exposure to possible very harsh working environment, the chassis is also the most vulnerable to damage and erosion. Rainy, snowy, and rugged mountain roads all might cause significant damage to the chassis. Therefore, timely inspection of the corrosion degree of the chassis is an effective way to protect the chassis.
