Graphite/titanium oxide composite anti-corrosion coating was applied on the surface of aluminum alloy. The surface morphology and composition of the coating were analyzed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The electrochemical properties of the coatings with different graphite additions were tested by potentiodynamic polarization curves and AC impedance. The coatings with five graphite content were prepared. The phases in the coatings are stable before and after corrosion, avoiding the volume change caused by structural transformation, so that these coatings have good adhesion and are not easy to fall off from the metal surface. As a filler, the graphite dispersed in the coatings extends the penetration path of the corrosive medium. The electrochemical analysis showed that the physical barrier effect of the coating was enhanced with the increase of graphite content, and the optimal addition amount was 2.5%. When the content of graphite exceeds this value, the barrier effect of the coating on the corrosion medium will be weakened due to particle agglomeration.

To analysis the effectiveness of different procedure of nursing coordination for phacoemulsification combined with intraocular lens implantation (IOL) surgery. Forty patients who received phacoemulsification combined with intraocular lens implantation surgery from Feb, 2014 to Sep, 2015 in the department of Ophthalmology in the First Affiliated Hospital of Jinan University were recruited for analysis. Patients were divided into two groups randomly: 20 patients with usual nursing procedure (the control group) and 20 patients in improved nursing procedure (the experimental group). The following parameters were collected: intraoperative swelling pain of the eye, operation time, complications of conjunctiva and cornea 1 and 7 days after the surgery, the position of IOL, intraocular pressure, visual acuity and the satisfactory level of surgeon and patients. The significant differences between the two groups were analysis by SPSS 19.0. Compared with the control group, the improved nursing coordination procedure showed less intraoperative swelling pain of the eye, shorter operation time, reduced corneal edema rate 1 day after the surgery, greater satisfaction of both the surgeons and patients. The improved nursing coordination procedure suggests success and safety of this combined surgery by shortening the operation time, reducing postoperative complications and improving the satisfaction of doctors and patients.
