  • Publication number: 20240093373
    Abstract: A method for preparing antibacterial stainless steel by surface alloying includes the steps of coating an infiltration promoter layer on a stainless steel surface, coating an antibacterial metal layer on a surface of the infiltration promoter layer, and performing heat treatment of the stainless steel to diffuse an antibacterial metal into the stainless steel. This method can be applied to various types of stainless steel, and the antibacterial metal can be diffused and quenched into the stainless steel, such that the finally formed surface of the stainless steel has an antibacterial alloy layer with a specific thickness to provide better corrosion resistance and antibacterial ability without changing the advantages and properties of the antibacterial metal or stainless steel substrate, and the thickness and concentration of the antibacterial metal layer, and the parameters for heat treatment can be adjusted to control the chemical composition and thickness of the antibacterial alloy layer.

  • Patent number: 9739802
    Abstract: A multi-electrode conductive probe, a manufacturing method of insulating trenches and a measurement method using the multi-electrode conductive probe are disclosed. The conductive probe includes a base, a plurality of support elements, a plurality of tips and a conductive layer. The base has a surface and a plurality of protrusions. The protrusions are configured on the surface in a spacing manner, and an insulating trench is disposed between the two adjacent protrusions. The support elements are disposed at the base and protrude from the base. The tips are disposed on the end of the support elements away from the base. The conductive layer covers the surface of the base, the protrusions, the support elements and the tips. Portions of the conductive layer on the two adjacent support elements are electrically insulated from each other by at least an insulating trench.

  • Patent number: 8578511
    Abstract: A thermal probe includes a support element, a conductive pattern and a tip. The support element has a slit or a through hole and has a first surface and a second surface which is opposite to the first surface. The conductive pattern is disposed at the first surface. The tip has a base and a pinpoint. The pinpoint is disposed at the base and passes through the slit or the through hole and highlights from the first surface. The base is connected with the second surface. The tip of the thermal probe of the invention can be replaced, and user can choose the best combination of the tip, conductive pattern and support element according to their needs.
