20160131567 | METHOD AND APPARATUS FOR DETERMINING CLEANLINESS OF A SAMPLE - A method and apparatus for determining cleanliness of a sample is provided. The method includes taking a first reading of particles count of a sample placed into a chamber. The method further includes directing a stream of air over the sample, and taking a second reading of particles count of the sample. The method further includes calculating a difference between the first reading and the second reading, and determining a cleanliness of the sample based upon the difference. The method further includes option of taking an additional reading while a stream of ionized air is directed towards the sample. The method further includes trapping the impurities particles released from the sample by applying a vacuum through the filter, and analyzing the trapped particles to determine nature and chemical composition of the impurities particles. | 05-12-2016 |

20120321812 | PROCESS FOR FORMING POROUS METAL COATING ON SURFACES - Embodiments of the invention provide a thermal spray method of forming a protective and porous coating over desired surfaces. Further, embodiments provide a thermal arc spray method, such as twin wire arc spray, to coat the surfaces. The invention may refer to using Aluminium and Silicon alloy in a twin wire arc spray method, to create sacrificial and protective coatings on the surfaces, such as substrates and machine parts. Machine parts may be, for example, of sputtering system. The method may utilize a predefined range of Silicon to be alloyed with Aluminium to improve the physical properties of the Aluminium, and further avoid damages to the coated surface, such as de-lamination and flaking of the coatings and coated surfaces. Additionally, generation of defects during a sputtering process may be efficiently reduced. | 12-20-2012 |
