Expatial

Expatial (short industry name for Expatial Technology) is an industry term derived from a combination of the Greek 'ex or
'ek signifying 'out of' and Latin 'spatium' meaning 'space (occupied).' Expatial meaning 'originating from within' or in the context of hardening amorphous crystal lattices, "strength originating from within the substrate, not a veneer." The term is generally used to describe a proprietary patented method, technology and applications set employed to harden steel and other lattice based working metals, developed by Extreme Performance Alloys, Inc. in 2011. Expatial Technology is a process whereby specific combinations of valence refractory actives are combined with Boron and working substrates to produce extraordinarily durable (specific hardness, purity, chemical resistance, corrosion resistance, abrasion resistance, wear robustness, impact resistance, high temperature performance and dynamic plasticity measures) working metals. The technology involves a process supported by apparatus, chemical mixes, a reactor, and specific environments which produce unprecedented levels of metal durability. Expatial Technology is distinguished from its older refractory metal deposition technology predecessors, Sputtering, Chemical and Vapor Deposition by its ability to modify the metal substrate as well as atomically bond durable coatings in 9 primary refractory metals. It involves no chemical ion deposition, target bombardment, nor vapor suspension. The process currently is proprietary and not available by license. As well the process results in extraordinary levels of purification of these same primary refractory metals, as part of the effect involved in the resulting surfacing.

Expatial hardening is a method of [. Knoop Hardness measures of 3000 or more have been attained in March 2011, by Extreme Performance Alloys Labs of Ft. Pierce, Florida (summaries and external lab confirmations for publication later this year). This hardness provides advantages in that not only are surface hardness characteristics attained similar to those of ceramic applications, but the hardened component retains the malleability, structural and conductivity performance characteristics of the original substrate or component. The resulting component is not susceptible to pulverization as are ceramic applications. This makes the technology ideal for components where ceramics (Boron Carbide) and non-amorphous crystals (DLC - Diamond like Coatings) do not perform well in structural and machined component environments.
