Catalysis of aluminum carbide formation at model

However, around 25 vol% graphite, the coefficient of friction levels off at a value of 0.2-0.25 and becomes almost independent of graphite content at graphite contents higher than 25 vol%. Wear resistance increases with the volume fraction of graphite particles as reflected in the reduction of weight loss by a factor of 4-5 as a result of dispersion of graphite particles until a volume more

PECVD Boat Maintenance Upgrade

PECVD Boat Maintenance Upgrade centrotherm PECVD systems are designed to ensure maximum system uptimes. Given that the deposition is limited to the wafers and graphite boats, the process tubes are only marginally impacted by parasite coating and have to be cleaned fairly once a year.
