We Are Particle Experts Particulate matter (PM) covers a wide range of finely dispersed solids that originate from both mobile and stationary sources and vary widely in chemical and physical composition. Particle characterization, which is the identificaiton of the composition of the particulate, can lead to the source of pollution. Identifying the size will determine […]

Supporting Superalloys – A Unique Approach to Powder Metal Cleanliness

Post by:

Superalloys are nickel-based or cobalt-based alloys that are resistant to high temperatures, perform better, are corrosion and oxidation resistant, and last longer than other metals. Superalloy parts are traditionally produced from powdered metals (PM) using subtractive manufacturing techniques. These parts are most often used in heavy industry or in areas having a corrosive environment, as […]

Contamination in Current Manufacturing Processes Manufacturers are creating materials that have new characteristics and are using production technologies that incorporate new processes. These new variables affect the quality of the finished product. With more complex products comes the possibility of contaminants that, when discovered, warrant not only an investigation, but an integrated analytical program that […]
