Introduction

Hong Siang Tan is a notable inventor based in Selangor, Malaysia. He has made significant contributions to the field of technology, particularly in the area of coating deposition. With a total of 13 patents to his name, Tan's work has advanced the understanding and application of composite coatings and plasma filtration.

Latest Patents

Among his latest patents, Tan has developed an enhanced macroparticle filter and a cathode arc source. This innovative cathode arc source is designed for depositing coatings on substrates. It features an anode and a cathode station for a target, along with a first filter means that includes a filter duct with at least one bend. The first magnetic means is utilized to steer plasma through the filter duct, effectively removing macroparticles from the plasma. Additionally, the apparatus incorporates a second filter for further macroparticle removal, which consists of a baffle and an aperture through which plasma can pass. The aperture size is designed to be less than 33% of the duct's sectional area at that point. The source may also include an ion beam generator, and a method for depositing coatings of ions using the second filter is described.

Another significant patent involves composite coatings, particularly those comprising carbon and a metallic element such as silicon or aluminum. These composite coatings exhibit improved properties compared to pure tetrahedral amorphous carbon coatings. They have reduced stress levels and can be deposited at greater thicknesses while maintaining acceptable hardness and other mechanical properties. The patent outlines methods for creating these composite coatings, the materials used, and the substrates that can be coated.
