| We designed and manufactured the equipment which can meet the moderate experimental production in this study. This equipment is consist of six parts, there are, electrocircuit control system, solution reaction system, ultrasonic clean system, blower drier system, SBF circular system and ion concentration's inspect system respectively. Then this equipment was debuged when it was completely manufactured. The test result showed that it has reached the expectant request.We used this industrial equipment to improve the process of HA growth on the titanium alloy surfaces. That is, after the simple heat treatment, the titanium alloy was orderly treated by alkali solutions with different concentrations, precalcified with saturated Na2HPO4 and Ca(OH)2 solutions, and last soaked in the SBF for 3 days. The morphology, phase composition and chemical composition of the oxide and apatite layers were characterized by field emission scanning electron microscopy (FE-SEM), low-angle X-Ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM).Thick and bioactive rutile-type TiO2 films were easily formed on the titanium alloy surface by heat treated in air at 600?C. After treated with alkali, the sodium titanate gel layer has form on the NiTi surface thereby shorten the formation period of the apatite nuclei. The results showed that the 3M NaOH treatment is the most appropriate method. A large number of apatite has formed within 1day's soaking in SBF. SEM, XRD and FT-IR results showed that the morphology and microstructure are highly similar to the human bone apatite. TEM results showed that the size of the nanocrystalline apatite is medially of 5×50 nm, with a needle-like shape, which is similar to that of the bone apatite.
