Title: HARDFACING ALLOY
Abstract:
The present invention relates to alloy compositions for protecting or re-finishing industrial tools which will be or have been exposed towear during use. Wear arises as a result of the normal cutting or drilling or similar operations of the tool. Large industrial tools which suffer wear include drill strings used in the oil and gas industry and the present invention is concerned with providing materials to overcome or reduce such issues. The issue of wear at contacting surfaces in engineering applications in general is a widespread problem and the invention provides alloys to address this problem.
