Xinhua News Agency, Madrid, May 25th Spanish researchers have successfully developed a new type of ceramic film that can be used as an antibacterial coating to effectively inhibit pathogenic bacteria on the surface of stainless steel products. It is expected to be used in medical devices, human implant materials, and public Health care facilities, food processing equipment and other fields.

Stainless steel has a wide range of uses due to its excellent rigidity, formability, and corrosion resistance. However, after repeated use and cleaning and disinfection of stainless steel products, the surface coating will wear, and bacteria such as Escherichia coli and Staphylococcus aureus can easily grow, leading to infectious diseases.

According to a communique issued by the University of Navarre, Spain, the research team led by the school’s engineer Javier Othesz developed a high-hardness ceramic coating in which a small amount of antibacterial metal such as silver and copper was added, and the coating was also applied. The layer has the advantages of high hardness, low coefficient of friction, good wear resistance and chemical stability. 
The communique said that using physical vapor deposition technology, researchers deposited a layer of uniformly dense ceramic film on the surface of a stainless steel substrate. This coating, on the basis of retaining the original characteristics of the stainless steel material, can prevent the growth of various pathogens, and has not found any side effects, and is particularly suitable for reducing the bacterial infection rate caused by surgical instruments and artificial limbs.

The researchers said that the ceramic antibacterial coating is durable and inexpensive, and is suitable for mass production( julep cup wholesales ). Closely related to daily life, sinks, cutlery, washing machine drums, surgical instruments, orthopaedic implants, etc. are expected to use this new material.
