Chapter 19: Problem 39

Steel hardware, including nuts and bolts, is often coated with a thin plating of cadmium. Explain the function of the cadmium layer.

Short Answer

Expert verified
Cadmium coating on steel hardware serves several functions such as corrosion resistance, durability enhancement, facilitating additional coatings or paint, and reducing friction, thus improving the assembly and disassembly procedures.

Step by step solution

01

Understand the context

In the case of steel hardware, such as nuts and bolts, a thin plating of cadmium is often applied. Consider why this coating is applied.
02

Explain the function

Cadmium is used due to its properties. It is corrosion resistant and it also provides additional strength. It reduces wear and tear on the steel hardware, making them more durable and efficient.
03

Provide additional insights

Cadmium also provides excellent adhesion for additional coatings or paint, providing a more comprehensive protective and aesthetically pleasing layer to the hardware items. It also facilitates smooth assembly and disassembly procedures as it reduces friction.
