Abstract:Abrasive powders are used in fine grinding and polishing applications many of which require defect-free surfaces. Scratching is a primary defect that can be caused by very low levels (less than 10 ppm) of large, oversize particles in the powders. Powders containing low levels of oversize particles can escape the scrutiny of quality control efforts because particle size analysis techniques have detection and sensing limits that prevent detection and quantification. This paper describes several common size analy… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
