One of the earlier described commercial methods for copper zinc water filtration is via kinetic degradation fluxion media (KDF), a product whose main filtration line consists of brass granules with varying proportions of zinc and copper alloy. [14] [15] It was developed in 1984 and patented by Don Heskett in 1987.
Operating a vacuum heat treating furnace, c. 1959–1962. A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination.

An owner's manual (also called an instruction manual or a user guide) is an instructional book or booklet that is supplied with almost all technologically advanced consumer products such as vehicles, home appliances and computer peripherals.
The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical properties of the ingredients. The purpose of sinter are to be used converting iron into steel. Sinter plants, in combination with blast furnaces, are also used in non-ferrous smelting.
Sintering or frittage is the process of compacting and forming a solid mass of material by pressure [1] or heat [2] without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms/molecules in the sintered material diffuse across the ...
Sintering metal-diamond compounds with direct hot presses goes back to the 1950s since when it is commonly practised in the diamond tool industry. Figure IV: Process layout of the co-sintering process; total cycle time 11.5 mins Key: Red/orange line: actual/set temperature Green line: densification of powder/green compact Dark blue/light blue ...
Hot isostatic pressing is thus also used as part of a sintering (powder metallurgy) process and for fabrication of metal matrix composites, [2] often being used for postprocessing in additive manufacturing. [3] The process can be used to produce waste form classes.
A vacuum arc remelting (VAR) furnace (or Arc Melter) from Edmund Buhler. VAR is used most frequently in high value applications. It is an additional processing step to improve the quality of metal. Because it is time consuming and expensive, a majority of commercial alloys do not employ the process.
