摘要:
为提高TA15钛合金的表面硬度和耐磨性,采用激光熔覆方法在钛合金表面制备了Ti/Ni+5%ZrO2涂层(质量分数),并对其组织和性能进行了研究.结果表明:熔覆层与基体结合良好;熔覆层中除了有 Ti2Ni 和 TiNi 金属间化合物之外还有少量的单斜相氧化锆(m-ZrO2)和四方相氧化锆(t-ZrO2);熔覆层中主要生成相 TiNi 和 Ti2Ni 可以极大地提高熔覆层的耐磨性和硬度,ZrO2相在提高熔覆层韧性的同时,进一步提高了熔覆层的耐磨性和硬度.%In order to improve the surface hardness and wear resistance of TA1 5 titanium alloy,Ti/Ni+5%ZrO2(mass fraction)coating was prepared by laser cladding method on the surface of TA15 titanium alloy.The microstructure and properties of the coating were studied.The results show that the cladding layer was well bonded with the substrate.Except of intermetallic compound Ti2Ni and TiNi,there were a small amount of monoclinic phase zirconia (m-ZrO2)and tetragonal phase zirconia (t-ZrO2)in the cladding layer.The wear resistance and hardness of the cladding layer were greatly improved by the phase of TiNi and Ti2Ni,and the toughness of the cladding layer was increased by ZrO2phase which further increased the wear resistance and hardness of the cladding layer at the same time.

摘要:
利用等离子旋转电极雾化技术制备出增材制造用球形TiNi合金粉末.利用扫描电子显微镜、X射线衍射和差示扫描量热法等分析手段对不同粒径的TiNi合金粉末表面及内部的显微组织、相组成和马氏体相变温度进行表征.实验结果表明,随着TiNi合金粉末粒度的逐渐减小,粉末表面的组织结构明显细化,且晶粒逐渐减小.另外,所有粒径的粉末以B2-TiNi相为主,且粒径≥178μm的粗颗粒粉末还含有少量Ti2Ni、Ni3Ti二次相.粗颗粒粉末内部少量二次相是在冷却过程中TiNi的共析反应产生的.在制粉过程中,不同粒度TiNi粉末的冷却速率不同.不同的冷却速率致使TiNi粉末的马氏体相变温度和马氏体相变路径不同.特别地,TiNi粉末的相变温度随粉末粒径的减小而降低.%This study aimed to produce spherical TiNi powders suitable for additive manufacturing by plasma rotating electrode process (PREP). Scanning electron microscopy, X-ray diffractometry and differential scanning calorimetry were used to investigate the surface and inner micro-morphology, phase constituent and martensitic transformation temperature of the surface and inner of the atomized TiNi powders with different particle sizes. The results show that the powder surface becomes smoother and the grain becomes finer gradually with decreasing particle size. All the powders exhibit a mainB2-TiNi phase, while large powders with the particle size≥178μmcontain additional minor Ti2Ni and Ni3Ti secondary phases. These secondary phases are a result of the eutectoid decomposition during cooling. Particles with different particle sizes have experienced different cooling rates during atomization. Various cooling rates cause different martensitic transformation temperatures and routes of the TiNi powders; in particular, the transformation temperature decreases with decreasing particle size.

摘要:
The crystal structure, enthalpy of formation, cohesive energy, mechanical properties, Debye temperature and electronic structure of TiNi, Ti2Ni and TiNi3 intermetallic compounds were calculated by using first-principles ultrasoft pseudo-potential approach of the plane wave based on density functional theory (DFT). The calculated results show that three intermetallic compounds all have thermodynamic stability and are easy to form alloy. TiNi3 has the strongest alloys forming ability. The crystal structures of those intermetallic compounds are stable in energy and mechanics, the stability in descending order are as follows: Ti2Ni, TiNi, TiNi3. TiNi and Ti2Ni are ductile, and the ductility of Ti2Ni is significantly higher than that of TiNi. TiNi3 has a poor ductility. The 3d electronics are the mainly bonding electrons. As the increase of relative amounts of Ni in those intermetallic compounds, the average bonding electrons are growing, the strength of chemical bonds enhance, the metallicity weakens. This leads to gradually increase of the elasticity modulus, hardness and Debey temperature.%采用基于密度泛函理论(DFT)的第一性原理赝势平面波方法,计算Ti-Ni合金系中TiNi、Ti2Ni和TiNi3金属间化合物的平衡晶格常数、生成焓、内聚能、力学性质、德拜温度和电子结构。计算结果表明:TiNi、Ti2Ni和TiNi3金属间化合物均具有热力学稳定性且容易合金化生成,合金形成能力由强到弱的排序为TiNi3、TiNi、Ti2Ni;3种金属间化合物的晶体结构在能量上和力学上都是稳定的,结构稳定性由大到小排序依次为Ti2Ni、TiNi、TiNi3;TiNi和Ti2Ni为延性相(延展性Ti2Ni大于TiNi的),TiNi3的延展性较差;3d电子是TiNi、Ti2Ni和TiNi3金属间化合物的最主要的成键电子,在这3种金属间化合物中,随着Ni相对含量的增加,平均成键电子数增多,共价键的比例增加,化学键的强度增强,金属性减弱,从而使得其弹性模量、硬度和德拜温度均逐渐升高。

摘要:
Indentation and reciprocating wear tests are carried out to study dent and wear resistance of superelastic Ti-Ni alloys. The effect of loading rate on the superelastic behavior of TiNi under indentation loading is investigated and compared to a new generation of shape memory alloys, i.e., 60NiTi. Only limited amount of work has been done to investigate the dependency of superelasticity on loading rate of TiNi under localized compressive loads, but much work is directed towards understanding the effect of strain rate on tensile properties. Understanding the superelastic behavior helps to employ superelastic alloys in applications where high impact loading is expected as in bearings and gears. In the present study, it is found that dent resistance of Ti-Ni alloy is not significantly affected by loading rate (within the employed loading conditions). It has also been found that new-generation 60NiTi alloy exhibits superior wear and dent resistance, as well as higher hardness compared to equiatomic TiNi.
