  • Surface treatment method of magnesium alloy article and structure thereof
    Patent number: 8894777
    Abstract: A surface treatment method of a magnesium alloy article includes, instead of forming a primer on a magnesium alloy based composite first, directly performing a hairline finish process on the magnesium alloy based composite, to form a hairline structure on a surface of the magnesium alloy based composite, and performing a chemical oxidation process on the magnesium alloy based composite, to form a glossy film covering the hairline structure on the magnesium alloy based composite, thereby forming a magnesium alloy article structure. Alternatively, another chemical oxidation process is performed before the hairline finish process, to form an oxide film on the surface of the magnesium alloy based composite.
    Type: Grant
    Filed: September 25, 2011
    Date of Patent: November 25, 2014

  • Method and system for detecting tool errors to stop a process recipe for a single chamber
    Patent number: 7908024
    Abstract: A method for detecting tool errors to stop a process recipe for a single chamber is disclosed. When a recipe error for one of chamber of a process tool is detected, only the chamber with the recipe error is terminated and other chambers are allowed to proceed with their recipe processes for preventing excursions.
