Physico-chemical properties of titanium
Technical characteristics
Titanium is a light silvery metal element of group IV of the periodic system of D. I. Mendeleev. Opened in the late XVIII century
Chemical symbol | Ti |
Atomic number | 22 |
The atomic weight | 47,867 |
Oxidation | 2, 3, 4 |
Melting point | 1670 °C (1943°K) |
Boiling point | 3560°K |
Its plasticity — the same of copper, and the level of creep is the same as that of stainless steel. Exceptional durability, heat resistance, specific strength has made this metal is indispensable material.
Strength
Although the mechanical strength of titanium at normal temperature is high enough, but with increasing temperature up to 250 °C the strength is lost by almost half. The situation save titanium alloys, in which this disadvantage disappears.
Corrosion resistance
This metal has excellent corrosion resistance. Corrosion resistance is evaluated by the amount of losses with 1 sq. meter of surface.
Corrosion resistance | weight losses of C1 sq meters | Score |
---|---|---|
Exceptional | Less than 0.001 g | 1 |
Very high | 0,001 — 0,005 | 2 |
0.005 — 0.01 g | 3 | |
good | 0,01 — 0,05 g | 4 |
0.05 — 0.1 g | 5 | |
Satisfactory | 0.1 — 0.3 g | 6 |
Small resistance | Of 0.3 — 1.0 g | 7 |
1 — 5.0 g | 8 | |
Minor | More than 5 g. | 9 |
In the conditions of an air aeration titanium is subject to corrosion in formic acid of any concentration up to 100 °C temperature, whereas without aeration is quickly destroyed by corrosion in a 25% solution of formic acid.
