Surface roughness is very important for most surfaces involved in sliding contact because factors such as the original rate of wear and the nature of the duration are highly dependent on this characteristic. These surfaces are generally load-bearing and need to be marked roughness to ensure ... Read More

17-4PH stainless steel (ASTM) is a martensitic precipitation-hardening stainless steel, equivalent to the national standard 05Cr17Ni4Cu4Nb. This type of stainless steel has a low carbon content and high Ni and Cr content, making it weldable with good corrosion resistance. Additionally, the steel ... Read More

What is stainless steel? Stainless steel is a type of steel. Steel refers to materials containing less than 2% carbon (C), while anything with more than 2% carbon is iron. During the smelting process, alloying elements such as chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), ... Read More

We talked recently about ion implantation, for example: Why ion implantation? Why do you have to deviate from a certain Angle when you inject ions? However, the implementation of this technology inevitably causes damage to the crystal structure of silicon wafers. This damage originates from atomic... Read More

After the gear has completed the heat treatment process (such as carburizing and quenching, induction hardening or nitriding), its surface hardness, core hardness and microstructure distribution directly determine its fatigue strength, wear resistance and overall life. In order to ensure that the ... Read More

Quenching, as an important metal heat treatment process, is widely used to improve the hardness, wear resistance, and fatigue strength of metal materials. However, bending deformation during quenching is a common and challenging issue. It not only affects the dimensional accuracy and shape stability ... Read More
