Through designing of composition and structure of the bioactive graded coating,innerstress and its distribution in the coating were analyzed and calculated, the resultsshowed that when composition distribution coefficient n was 1.5, a reasonable stressdistribution could be got, that was at the beginning of deposition the suspension containingrichly BG granules was used so that a rich BG granules layer, a good transitional layerbetween BG layer at the bottom and the coating could be obtained at the titanium alloy side,the bottom of the coating; the stress value near the interface and surface and its character,pressure stress or tensile stress, were decided by the character of its composition itself.Changing composition distribution coefficient n could only change the variation tendency ofstress in the coating, but did not change the stress distribution rule in the coating. Thethinner the coating is, the sharper stress variation in the coating is, which does not mean thatthicker coating is better because the thicker the coating is, the little the permitteddeformation of coating is, so the coating thickness should be thinner, for example, about50μm for bending applications, but for applications only bearing pure shear stress, such asroot of tooth implant, the coating can be thicker little, for instance, about 80~100μm. The study on electrification characteristic and electrophoresis deposition of HAand BG granules in aqueous and non-aqueous solution system found that EPD almost didn'toccur in aqueous solution system. However, because HA granules take position charges inabsolute alcohol, a homogeneous EPD be carried out on the cathode titanium alloy slice, but taking negative charge in absolute alcohol the BG granules not be deposited on the cathode. A guided HA crystallizing, 100~300nm, on surface of the BG granules be realized by metathetical reaction, which cover BG granules with HA microcrystals and make the covered BG granules taking position charges in absolute alcohol, sequentially realize the EPCD of the BG and HA granules on the cathode, so it is feasible to make a titanium alloy/BG/HA bioactive graded coating by making use of EPCD technology. The corrosion experiment of rich boron bioglass coating and plasma spray coating showed that split phase, rich boron and rich silicon phase, occurred during its preparation. In basic medium the corrosion behavior of 〓 BG coating showed uniformity corrosion, the corrosion mostly occurred at rich boron phase area, therefore batch formula design of BGshould avoid the occurring of split phase. The corrosion appearance of plasma spray coatingappeared a non-uniform corrosion, mostly occurred at the edge of the laminated HA moltendrops, and emerged an accelerated corrosion tendency, which will easyly lead to corrosioncrackles extending to the interface and the happening of osmotic interfacial corrosion, thatmay be one of the major reasons leading to the coating cracking-off in the later period. Thetesting results of thermal expansion coefficient of 〓 and 〓BG showed the thermalexpansion coefficient of 〓 BG matched with that of titanium alloy better, and 〓 BG couldsinter with titanium alloy into densification enamel layer at low temperature (720℃).
将Ti6Al4V合金在1000℃下进行真空热处理会降低其力学性能,且合金内的V元素会向表面富集,因此,钛合金真空热处理和表面涂层的烧结温度不能过高,即应低于其相转变点;通过对生物活性梯度涂层的组成和结构的设计,分析和计算了梯度涂层内的应力大小和分布,结果表明:对于本研究,当成分分布系数n=1.5时,可以获得较合理的涂层力学性能,即在沉积开始时,采用富含BG颗粒的悬浮液,以便在钛合金侧获得同底层BG有良好过渡的富BG涂层;梯度涂层界面和表面的应力大小、性质由材料组成本身的性质决定,改变成分分布系数,只能改变涂层内应力变化的趋势;涂层的厚薄不影响涂层内的应力分布规律,但涂层越薄,涂层内的应力变化越快,但这并不意味着涂层越厚越好,因为涂层越厚,涂层允许的变形越小,对于应用于弯曲受力部位的涂层而言,涂层应薄一点为好(50μm);而对于仅纯受剪切应力的部位,如牙根种植体,涂层可适当加厚(80~100μm);通过对HA和BG颗粒在水溶液体系和非水溶液体系中的带电特性和电泳沉积的研究发现,它们在水溶液体系中很难发生电沉积;在无水乙醇溶液中,HA颗粒带正电,可在阴极钛合金片上发生均匀的电泳沉积,而BG颗粒则带负电荷;利用复分解反应法,可以制得100~300nm的HA,通过诱导HA在BG颗粒表面结晶,可对BG颗粒进行表面包覆,获得了被HA包覆的BG颗粒,改变了BG颗粒表面的带电特性,使BG和HA颗粒在无水乙醇中均带上正电荷,从而实现了HA和BG颗粒在阴极上的共沉积。

A series of erosion-corrosion test has been done to J55 steel under the influence of current of gas-liquid phase by indoor self-made devices, and the corrosion mechanism of current of gas-liquid phase to oil pipe's inner surface has been got. The results show that oil pipe's inner surface will be corroded fleetly by liquid medium and corrosion products will form on it. But at the same time, the corrosion products or protective layer will be removed from the inner surface of steel pipes under the alternate impact of high speed gas and liquid flow, and on this bare steel surface corrosion film will form again and be removed again. Thus, by these ways the corrosion is exacerbated. Surface erosion-corrosion failure comes into being with the circulation of this process going on.
本文主要在气液两相流作用条件下,通过室内自制装置,对管材钢J55做了系列冲刷-腐蚀试验,结果表明,气液两相流对钢管内表面冲刷-腐蚀的机理是钢管内表面会受到液体介质的快速腐蚀,生成腐蚀产物,同时钢管金属表面不断被具有高流速的气液相交替地冲击,不断地从金属表面脱去保护膜或腐蚀产物,裸露的钢表面又会被介质快速腐蚀形成腐蚀膜后,再被两相流冲掉,如此反复,造成管内金属表面膜的连续破坏,使腐蚀加剧,最终导致钢铁表面的冲刷腐蚀失效。
