About Cold Nano-Fusion™ Alloy Technology
What is it exactly?
- An advanced low-energy surface alloy formation technology that enables engineers to create specialty alloy layers on metal parts - especially on metals that cannot be conventionally welded.
- During the build-up of the alloy surface, Advanced Surfaces' proprietary equipment produces a computer controlled, pulsed plasma arc which transfers nanometer-sized (one billionth of a meter) packets of molten electrode metal which combine with the base metal to form a new alloy.
- Over 30 important variables have been identified that are controlled to produce a range of desirable properties.
- All conducting metals and cermets can be treated (except gray cast iron)
- True Metallurgical Bond - With NanoFusion, the molecules of the two metals actually intermingle and combine together. This is in contrast to the coating processes (e.g. flame spray or chrome plating) which sit on top of the base metal and adhere to it but do not become molecularly mixed (see photo top right).
- Extreme Hardness Levels - The molten nano-packets cool/coalesce in less than one millionth of a second. This influences the formation of an extremely fine grain structure with interboundary grain growth. This highly desirable effect is a major factor in achieving high hardness, strength and corrosion resistance levels- in combination with proper formulation of the electrode (among other variables). Measured hardness levels are off the top of both Rockwell B & C hardness scales.
- Alloy formation at ambient temperature - The base metal of the part remains cool with no thermal stresses and/or chemical changes introduced. One can actually touch the part with a bare hand immediately after treatment and feel that the surface is still at ambient temperature.
- Engineering "special effects" - Over 30 different variables are manipulated to promote different types of grain growth and physical surface effects. It was the characterization of these complex interactions, over years of research, that led to the development of our technology for controlling these effects to solve special metallurgical problems.
- Large areal coverage - Primarily an economic limit. Large areas, i.e. on the order of dozens of square feet, may be economically practical for some applications.
- Gray cast iron - Gray cast iron cannot be treated (note: ductile cast iron can be treated).
