titanium alloy rod
(1) The corrosion resistance of titanium is affected by the surface oxide film, so this material is more suitable for use in oxidizing environments, or places where oxygen is easily available. In reducing solutions, titanium will react with the solution to generate hydrogen.
(2) Like all metals, when titanium is in direct contact with different metals in the electrolyte, a galvanic couple will form. After the galvanic couple is formed, one or both metals corrode much faster than before the galvanic couple is formed. In almost all cases, titanium is the more inert pole of the galvanic couple, thus causing corrosion of the other metal. Increase. The degree of corrosion depends on the relative area ratio and the actual electrolyte used. Therefore, the formation of galvanic couples should be avoided when designing equipment.

(3) Some titanium alloys with good high-temperature strength have been produced, but compared with pure titanium, these alloys have poor corrosion resistance. Titanium alloys with good corrosion resistance include titanium-palladium and titanium-nickel-molybdenum alloys.

(4) Generally, titanium is only used in some situations where the corrosion rate is very slow. Therefore, when designing equipment, there is no need to provide a corrosion tolerance margin. In this way, it is possible to use relatively thin titanium plates as bushings for carbon steel containers, heat exchanger tail boxes and tube sheets, pumps, valves, etc. - thin titanium tubes can also be used for tubular heat exchangers and thin titanium plates for plate heat exchangers. exchanger to reduce equipment costs and improve heat exchange performance.
