    • To apply a thermal barrier coating (10), a plasma jet (5) is generated by a plasma torch in a work chamber (2) and is directed to the surface of a substrate (3) introduced into the work chamber, and a ceramic coating material is applied to the substrate surface by means of PS-PVD, wherein the coating material is injected into the plasma jet as a powder and is partly or completely vaporized there. On applying the thermal barrier coating, in a first workstep the feed rate of the injected powder is set so that a large part of the injected powder vaporizes, wherein the coating material condenses from the vapor phase on the substrate surface and forms mixed phases with the material of the substrate surface. In a second workstep, the feed rate of the injected powder it increased by at least a factor of 5, whereby the portion of the powder which vaporizes is reduced and the coating material is deposited in the form of elongate columns which form an anisotropic microstructure and which are aligned substantially perpendicular to the substrate surface.
    • 为了施加热障涂层(10),通过工作室(2)中的等离子体焰炬产生等离子体射流(5),并且被引导到被引入到工作室中的衬底(3)的表面,并且陶瓷 通过PS-PVD将涂料施加到基材表面,其中将涂料作为粉末注入等离子体射流中,并在其中部分或完全蒸发。 在施加热障涂层时,在第一工作步骤中,注入的粉末的进料速率被设定为使得大部分注入的粉末蒸发,其中涂层材料从衬底表面上的气相冷凝并形成混合相, 基材表面的材料。 在第二个工作步骤中,注入的粉末的进料速率增加至少5倍,从而减少蒸发的部分粉末,并且以形成各向异性微结构的细长柱的形式沉积涂层材料, 其基本上垂直于衬底表面对准。

    • According to at least one aspect of the present invention, a method is provided for forming a polymerized coating on a surface of a substrate. In at least one embodiment, the method comprises providing a plasma gun having an outlet; introducing a pre-polymer molecule into the outlet of the plasma gun to form a number of fragments of the pre-polymer molecule as a plasma output including a direct-spray component and an over-spray component; at least partially isolating the direct-spray component and the over-spray component from each other to respectively obtain an isolated directed-spray component and an isolated over-spray component; and depositing at least a portion of the isolated direct-spray component and the isolated over-spray component onto the surface of the substrate through the outlet to form a base polymerized coating. The plasma gun is optionally operated at atmospheric pressure.
    • 根据本发明的至少一个方面,提供了一种在基材表面上形成聚合涂层的方法。 在至少一个实施例中,该方法包括提供具有出口的等离子体枪; 将前体聚合物分子引入等离子体枪的出口以形成预聚物分子的许多片段作为包括直接喷射组分和过度喷射组分的等离子体输出; 至少部分地将直接喷射组分和过度喷射组分彼此分离,以分别获得分离的定向喷射组分和分离的过度喷射组分; 以及通过出口将分离的直接喷射组分和分离的过度喷涂组分的至少一部分沉积到衬底的表面上以形成基底聚合涂层。 等离子体枪可选地在大气压下操作。
