  • destruction of Coating Material during spark anodizing of titanium
    Electrochimica Acta, 2006
    Co-Authors: Endzhe Matykina, G. Doucet, F Monfort, A Berkani, Peter Skeldon, G. E. Thompson
    Abstract:

    An investigation has been carried out, using a sequential anodizing procedure, of the loss of Coating species to the electrolyte during spark anodizing of titanium. Anodic Coatings were formed galvanostatically in alkaline silicate electrolyte and then further thickened by re-anodizing in alkaline phosphate electrolyte. In addition to examination of Coating compositions and morphologies following different times of anodizing in each electrolyte, solution analyses for silicon and titanium were carried out subsequent to anodizing in the phosphate electrolyte. Significant amounts of both elements were detected, indicative of destruction of the Coating at sites of dielectric breakdown in the phosphate electrolyte. The lost Coating Material is replaced by formation of phosphorus-rich Material at the breakdown sites, as evident from elemental mapping of Coatings.

  • self cleaning and antibacterial silicane coated polyurethane artificial leather
    2017
    Co-Authors: Zhu Guanghe
    Abstract:

    The invention relates to self-cleaning and antibacterial silicane coated polyurethane artificial leather. The surface of a polyurethane substrate is coated with a layer of a silicane Coating Material, and the silicane Coating Material is solidified. The silicane Coating Material is prepared by mixing a reactor with one or more kinds of silicane not precondensated or partially precondensated. The molecular weight of silicane is greater than 200. Silicane has a polar group suitable for forming a hydrogen bridge band in an organic side chain. After the surface of the polyurethane artificial leather is protected by the silicane Coating Material, the polyurethane artificial leather has better self-cleaning and antibacterial characteristics, and the use quality of the polyurethane artificial leather is improved.

  • Study of the System Wood – Coating Material. I. Wood – Liquid Coating Material
    Holzforschung, 2000
    Co-Authors: Eva Liptáková, Jozef Kúdela, Jukka Sarvas
    Abstract:

    This paper deals with the evaluation of wood - wetting process with Coating Materials on the basis of interactions of surface forces on phase boundary. The obtained results are compared with the actual state in the system wood - Coating Material. Primary ability of Coating Materials - spontaneous spreading over the wood surface has been proved. There is also the secondary influence of rheological properties of Coating Materials causing deformations of the phase boundary, non-perfect wetting of the wood surface and apparent lowering of adhesion work. The influence of rheological properties has been expressed by using the coefficient F the meaning of which follows from the comparison between results of adhesion work computed according to modified Young-Dupre equation and of adhesion work determined on the basis of the interactions of surface forces on the phase boundary between wood and liquid Coating Materials. A direct dependence between the values of the coefficient F and Coating Materials viscosity has been proved.

    Co-Authors: Eva Liptáková, Jozef Kúdela, Jukka Sarvas
    Abstract:

    Summary This paper deals with the evaluation of wood—wetting process with Coating Materials on the basis of interactions of surface forces on phase boundary. The obtained results are compared with the actual state in the system wood—Coating Material. Primary ability of Coating Materials—spontaneous spreading over the wood surface has been proved. There is also the secondary influence of rheological properties of Coating Materials causing deformations of the phase boundary, non-perfect wetting of the wood surface and apparent lowering of adhesion work. The influence of rheological properties has been expressed by using the coefficient F the meaning of which follows from the comparison between results of adhesion work computed according to modified Young-Dupré equation and of adhesion work determined on the basis of the interactions of surface forces on the phase boundary between wood and liquid Coating Materials. A direct dependence between the values of the coefficient F and Coating Materials viscosity has been proved.

  • Study of the system wood-Coating Material. Part 2. Wood-solid Coating Material
    Holzforschung, 2002
    Co-Authors: Eva Liptáková, Jozef Kúdela
    Abstract:

    Summary This paper deals with the intermolecular forces in the system wood-solid Coating, which primarily condition the stability of the system. Further, it points out a series of secondary factors that significantly distort the results of interactions between surface forces; not only influencing the phase boundary wood-Coating Material in the liquid phase, but also negatively impacting the wood-solid Coating system stability.
