    • The behaviour of the α/β Ti6A14V and Ti6A17Nb alloys and of the α, c.p. Ti upon spark anodisation in H2SO4, H3PO4 and mixtures of these acids is presented. Chemical depth profiling reveals purified oxides with respect to the substrate alloying elements. This is particularly pronounced on Ti-alloys spark anodized in H2SO4ZH3PO4 mixtures, with Al decreasing continuously towards the surface, and V and Nb remaining hardly detectable in the outermost 200 nm. In addition, the incorporation of S was significantly reduced in mixed electrolytes, while about 8 at-% P was incorporated. A novel oxide morphology with "worm-like" features in the μm-range, very different from well-known nano/micro-porous oxides, was found in mixed electrolytes under optimized conditions. A similar but more porous-like structure is formed on c.p. Ti. Raman measurements indicate the presence of mixed anatase, rutile and brookite phases on anodized Ti-alloys. Bond strengths of 34 MPa for worm-like and 40-50 MPa for nano/micro- porous morphologies as well as excellent abrasion behaviour characterized the mechanical properties of the oxides. The compatibility of grit-blasting and etching of surfaces with the spark anodisation process for creating multi-topography surfaces is confirmed.
    • α/βTi6Al4V和Ti6Al17Nb合金的性能以及α,c.p. 提出了H2SO4中的火花阳极氧化后的Ti,H3PO4和这些酸的混合物。 化学深度剖析揭示了纯化的氧化物与基底合金元素的关系。 这对在H2SO4ZH3PO4混合物中阳极氧化的Ti合金火花尤其明显,Al向着表面不断地减少,并且在最外面的200nm处几乎不能检测到V和Nb。 另外,混合电解质中S的掺入显着降低,而掺入约8原子%P。 一种新的氧化物形态具有“蠕虫状” 在优化的条件下,混合电解质中发现了μm范围内的特征,与众所周知的纳米/微孔氧化物非常不同。 在c.p.上形成了类似但更多孔的结构。 钛。 拉曼测量表明在阳极氧化钛合金上存在混合锐钛矿相,金红石相和板钛矿相。 纳米/微米多孔形态的粘合强度为34 MPa,螺旋状和40-50 MPa,以及优异的耐磨性表征氧化物的机械性能。 证实了喷砂和表面蚀刻的兼容性以及用于创建多形貌表面的火花阳极氧化过程。

    • Method for metallizing the surface of an object, for example a plate (20) of ceramics or other inert material, of stone, wood, plastics. The process begins with the location of the plate (20) in the vicinity of means for delivering molten metal (1), towards which a metal supply is fed in the form of metal wires (2 and 3) for example through guided by sheaths (4). In the means for melting (1) and in particular at melting site (15) the melting occurs of the metal source (2 or 3) . This can be carried out by discharging an electrical arch between two electrodes, or between an electrode and a metal wire that in this case works as second electrode, or still discharging an electrical arch directly between the metal wires (2 and 3) . Alternatively, the melting of the metal wire (2 or 3), can be executed using a combination of a 20 current of gas fuel and a current of a comburent gas burning at high temperature at the melting site.

    • The invention relates to mechanical and material engineering and can be used for improving operational characteristics of surfaces of articles made of aluminium and aluminium-silicon alloys. The inventive method for coating articles made of aluminium silicon containing alloys consists of alloy pre-treatment and a micro-arc oxidation. Said alloy pre-treatment is carried out until a structure is formed in which particles of silicon-containing phases are arranged in the form of individual inclusions and/or the chains thereof in such a way that a mean distance between boundaries of the adjacent silicon-containing inclusions on the flat section of material exceeds 5 % of a mean linear dimension of the inclusions. Said invention makes it possible to improve adhesion and mechanical bond between the coating and the oxidised alloy and optimise said alloy with respect to practical operating requirements. The invention also reduces power consumption.

    • The invention relates to a new construction material which is based on aluminium and has high mechanical characteristics, wear and corrosion resistance, a heat stability and which can be produced by using a relatively cheap technology. The inventive material comprises a casting aluminium alloy whose composition and structure favour to obtain a quality surface hardening with the aid of the plasma electrolytic oxidation method and a hard oxide-ceramic coating produced with the aid of said method. The aluminium alloy contained in the inventive construction material represents a multiphase eutectic alloy, which comprises an alloyed matrix (of a hard aluminium alloy) reinforced by dispersed hard spots of a crystallisation nature and products of the matrix decay which are evenly distributed through the volume of said aluminium alloy. The properties of the aluminium alloy can be controlled by modifying the concentration of alloying elements, the cooling speed and a heat treatment schedule. In order to cast articles from said alloy traditional methods for casting into metallic moulds are used. The protecting ceramic coating which is formed on the surface of the casts from said alloys has a high degree of strength, microhardness, density and of the evenness of thickness.
