Now more common to use titanium hard disk on TC Titanium the market specifications: diameter 95mm thickness 0.8mm 0.635mm or look hardness 14700MPa Young's modulus 660GPa maximum operating temperature of 700 ℃; flatness <10μm roughness Ra <0.8nm disc used Production technology for precision cold-rolled titanium or more titanium rod and titanium alloy, the outer disc by plasma nitriding, plasma nitriding or plasma nitrocarburizing hardened disposal, the disc outer layer of titanium nitride may also be sprayed or titanium boride hard coat layer.
develop rapidly. 1998 world production of about 450 million discs. Analysts predict a huge market computer's hard disk. Hard disk production by 10% -15% annual growth rate. It is estimated that, with the intense competition and the rapid development of information industry market, the titanium used in computers will have a better market.
So titanium used in personal computers, mobile phones and other areas is increasing. Titanium used on a computer is mainly used as computer housings, and hard disks. Because titanium has a light weight, no metal allergy can be recycled, and many other fine features. Not only improves the strength and seismic performance chassis, IBM in May 2000 the company announced that its new ThinkPad notebook computer casings titanium matrix composites. A series of ThinkPad computers (such as A20p and T Series (T20 chassis was used as titanium matrix composites. And the computer can be thinner and lighter.
Fujitsu pioneered the use of titanium (99.5% manufacture of small A5 size, 890 grams lightweight laptop case. 1999 The company has a titanium rod and titanium alloy (on INTERTOPCX300 housing in the laptop. So in the realization of titanium as Titanium round bar housing data thinned while maintaining strength, tensile strength than titanium case primarily as computer data much higher magnesium (magnesium-titanium 106.3GPa titanium 44.4GPa thermal conductivity (17W / mK only magnesium (159W / mK one-tenth. suppress diffusion of heat from the hardware, etc., to prevent the underside of the fever, especially due to the appearance of excellent corrosion resistance of titanium, the appearance of the coating becomes relatively simple disposal.
