Patent number: 10781512Abstract: A method for coating a body includes providing a plurality of granules in which each granule includes silicon (Si), carbon (C), chromium (Cr) and an iron group metal. The relative quantities of the Si, C and Cr are such that a molten phase will form at a melting temperature of less than 1,300 degrees Celsius when a threshold quantity of the iron group metal is accessible to the Si, C and Cr. A second source of the iron group metal is also provided. A combination of the granules and the second source is formed such that the threshold quantity of the iron group metal will be accessible to the Si, C and Cr. The granules and the second source are heated to the melting temperature to form the molten phase in contact with the body. The heat is then removed to allow the molten phase to solidify.Type: GrantFiled: May 22, 2015Date of Patent: September 22, 2020Assignee: Element Six GmbHInventors: Igor Yurievich Konyashin, Daniel Hlawatschek, Bernd Heinrich Ries

Patent number: 10677054Abstract: A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.Type: GrantFiled: July 29, 2016Date of Patent: June 9, 2020Assignee: Joy Global Underground Mining LLCInventors: Randy Arnold, James E.
