superhard
Beyond diamond toughness
Superhard describes materials of extreme hardness, typically those approaching or rivaling diamond on the hardness scale: superhard coatings for industrial cutting tools, superhard carbon compounds.
The term appears in materials science for substances that resist scratching and deformation under pressure.
In casual use, superhard is simply an emphatic form of hard: That test was superhard.
