Amorphous metals are alloys that contain atoms of significantly different sizes, leading to low free volume and therefore higher viscosity up to many orders of magnitude. This viscosity prevents the atoms from moving enough to form an ordered lattice (crystalline structure) like common metals. The absence of grain boundaries, the weak spots of crystalline materials, leads to better resistance to wear and corrosion. Amorphous metals are also much tougher and less brittle than carbon based metal alloys and ceramics.

Amorphous alloys have a variety of useful properties. In particular, they tend to be stronger than crystalline metals and they can sustain larger reversible (elastic) deformations than crystalline alloys. Amorphous metals derive their strength directly from their non-crystalline structure, which does not have any of the defects (such as grain boundaries & dislocations) that limit the strength of crystalline alloys.

Liquidmetal Coatings is the world leader in development of amorphous alloy solutions for wear and corrosion and holds a portfolio of technology patents. Our proprietary line of amorphous alloys are deployed as the top performing solutions to wear and corossion in many industries including: Oil & Gas, Power Generation, Pulp & Paper, Mining, and others where wear or corossion cause high matenaince costs, increased replacement costs or preventable downtime costs.

Amorphous metallic structures are fundamentally different from crystalline metals used since the beginning of recorded history.

Liquidmetal Coatings’ materials possess an amorphous atomic structure with no discernible patterns.  In contrast to crystalline metal structures, an amorphous atomic structure is random.  As such, properties superior to the limits of crystalline structures are achieved.

In the Crystalline Structure
 vacancies can collect and form voids within the material.  Dislocations are the source of movement under load that prevents crystalline alloys from achieving the theoretical strength inherent in an atom-to-atom bond.  Boundaries are very active in relation to surface energy and promote corrosion and chemical reactions such as oxidation and sulfidation.

In the Amorphous Structure
 alloy coatings form a structure very different from crystalline alloy coatings. In the amorphous structure, atoms are randomly placed in a continuous coating, obviating the corrosion-path grain boundaries. The lack of dislocations leads to favorable wear resistance to abrasive particles and metal-to-metal contact, non work-hardening, machinability and leads to a low coefficient of friction, near theoretical strength (and hardness) and outstanding resistance to cavitation. The lack of boundaries leads to improved corrosion resistance and resistance to reaction at elevated temperature (oxidation, sulfidation).
