Researchers studying the performance of diamond coatings have found a number of factors of the coating process that determine the ultimate success of the coating. This article looks at factors such as substrate preparation, stresses in the coating and substrate and the diamond coating's formation patterns.
The presence of an eta phase between a coating and the substrate is generally considered harmful to coating adhesion. However, this article argues that when the formation of the eta phase is carefully controlled, it can actually enhance adhesion. The conditions that promote the formation of beneficial eta phase are explained.
Researchers report on their study of coating performance. Their tests of TiN, TiCN and TiAlN coatings involved turning Inconel 718, medium-carbon steel and ductile cast iron. The wear rates and failure mechanisms of the coated tools are compared.
The PVD and CVD processes produce coatings with specific strengths and weaknesses. This article compares the processes and attempts to correct some common misconceptions about CVD coatings. The findings of a survey on tool coaters' use of coating materials and methods are also reported.
Vapor Technologies Inc. (VaporTech) announces the launch of the VT-i series PVD coating machines: Brand-new equipment that meets today’s needs for efficiency, cost-control, and product quality and differentiation.
Lucifer Furnaces delivered a large dual chamber unit to a metal stamping manufacturer in the Midwest. Model HL82-P24 is a hardening furnace over tempering oven, built as a space saving combination for multipurpose heat treating.
No. 797 is a 260º F (127º C), electrically heated, Class 100 clean room cabinet oven from Grieve, currently used for drying coatings onto printed circuit boards at the customer’s facility. Workspace dimensions of this oven measure 36” W x 36” D x 39” H.
To support growing demand, manufacturers have committed extensive resources to HSS tools, making them more reliable, with improved quality, lower production costs and shorter lead times.
