摘要： Described herein is a protective coating composition that provides erosion and corrosion resistance to a coated article (such as a chamber component) upon the article's exposure to harsh chemical environment (such as hydrogen based and/or halogen based environment) and/or upon the article's exposure to high energy plasma. Also described herein is a method of coating an article with the protective coating using electronic beam ion assisted deposition, physical vapor deposition, or plasma spray. Also described herein is a method of processing wafer, which method exhibits, on average, less than about 5 yttrium based particle defects per wafer.

摘要： A system (100), apparatus (110), and method (900) for creating a particle stream (70) that is deflected with a secondary gas (518) such as air before coming into contact with the treated substrate surface (80). The system (100) can be implemented as an improvement to a prior art PTWA (plasma transferred wire arc) thermal spraying apparatus (50) by using a non-symmetrical passageway configuration (549). Such a configuration can be an attribute of a nozzle (220) or a secondary gas director (576) such as an air baffle (578).

摘要： The present invention provides a thermal barrier coated component, monitoring or evaluation of the soundness of which is able to be adequately carried out on the basis of the thermal boundary conditions that are detected by a sensor. A thermal barrier coated component according to the present invention comprises: a base material; a first bond coat layer that is a metal bonding layer formed on the base material; a sensor unit that comprises a sensor and a conductive wire, which are formed on the first bond coat layer; a second bond coat layer that is formed on the first bond coat layer so as to cover at least the sensor unit, while having a surface roughness higher than that of the first bond coat layer; and a top coat layer that is formed on the second bond coat layer.
