People often ask why stainless steel, being stainless, can still rust. What is the mechanism behind its rust resistance? Is it safe to use as long as the material composition is correct? Let's delve into these questions one by one. While some advantages of stainless steel can become disadvantages ov

The initial permeability μi is a fundamental parameter of soft ferrite materials. In communication equipment, most electronic transformers operate at low flux densities, where the material's permeability plays a crucial role. When the material has a high permeability, a smaller number of turns in th

Nitrile rubber (NBR) is an elastomer made from acrylonitrile and butadiene, known for its excellent resistance to oil and fuel. However, due to the presence of carbon-carbon double bonds in its structure, it is susceptible to degradation by heat, oxygen, ozone, and strong chemicals, making it unsuit

Continuing from last week, today I would like to introduce micro-dynamic corrosion wear, the English name: Fretting.forewordThe introduction of micro-motion (corrosion) wear is primarily based on my previous work experience. For example, even though there is no obvious relative motion between two co
