Titanium's durability, light weight, and dent and corrosion resistance make it useful for watch cases. [115] Some artists work with titanium to produce sculptures, decorative objects and furniture. [123] Titanium may be anodized to vary the thickness of the surface oxide layer, causing optical interference fringes and a variety of bright colors ...
In the case of titanium, niobium, and stainless steel, the colour formed is dependent on the thickness of the oxide (which is determined by the anodizing voltage). Chemically coloring a metal is distinct from simply coating it using a method such as gilding or mercury silvering , because chemical coloring involves a chemical reaction, whereas ...
Heavy minerals (dark) in a quartz beach sand (Chennai, India).Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.
In metallurgy, exfoliation corrosion (also called lamellar corrosion [1]) is a severe type [2] of intergranular corrosion that raises surface grains from metal by forming corrosion products at grain boundaries under the surface. It is frequently found on extruded sections where grain thickness is not as thick as the rolled grain.
Titanium is considered the most biocompatible metal due to its resistance to corrosion from bodily fluids, bio-inertness, capacity for osseointegration, and high fatigue limit. Titanium's ability to withstand the harsh bodily environment is a result of the protective oxide film that forms naturally in the presence of oxygen.
The surface of titanium and of titanium-rich alloys oxidizes immediately upon exposure to air to form a thin passivation layer of titanium oxide, mostly titanium dioxide. [27] This layer makes it resistant to further corrosion, aside from gradual growth of the oxide layer, thickening to ~25 nm after several years in air.

The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
