Our Ag+W engineering team find that many anti-bacteria coatings available in the market are with uneven silver ions deposit on coating surface, causing to low sterilization function.
In 2016, we had a technology break through by using Physical Vapour Deposition (PVD) with help of mid-frequency sputtering coating technique. It forms a very beautiful coating on work piece surface. Our team uses tungsten to form a fundamental coating and then in-plant nano-silver particles into the coating. Both tungsten and silver have good sterilization function, synergies a dual effect to kill bacteria. In addition, the silver particles are protected by hardness of tungsten. It makes the Ag+W coating strong and long lasting.
