摘要： A method for providing a surface finish to a metal part includes both diffusion hardening a metal surface to form a diffusion-hardened layer, and oxidizing the diffusion-hardened layer to create an oxide coating thereon. The diffusion-hardened layer can be harder than an internal region of the metal part and might be ceramic, and the oxide coating can have a color that is different from the metal or ceramic, the color being unachievable only by diffusion hardening or only by oxidizing. The metal can be titanium or titanium alloy, the diffusion hardening can include carburizing or nitriding, and the oxidizing can include electrochemical oxidization. The oxide layer thickness can be controlled via the amount of voltage applied during oxidation, with the oxide coating color being a function of thickness. An enhanced hardness profile can extend to a depth of at least 20 microns below the top of the oxide coating.
摘要翻译：用于向金属部件提供表面光洁度的方法包括扩散硬化金属表面以形成扩散硬化层，并且氧化扩散硬化层以在其上产生氧化物涂层。扩散硬化层可以比金属部分的内部区域更硬，并且可以是陶瓷，并且氧化物涂层可以具有不同于金属或陶瓷的颜色，颜色不可仅通过扩散硬化或仅通过氧化。金属可以是钛或钛合金，扩散硬化可以包括渗碳或氮化，氧化可以包括电化学氧化。可以通过在氧化期间施加的电压量来控制氧化物层厚度，氧化物涂层颜色是厚度的函数。增强的硬度分布可以延伸至低于氧化物涂层顶部至少20微米的深度。

摘要： A process is disclosed for minimizing the difference in thermal expansivity between a porous anodic oxide coating and its corresponding substrate metal, so as to allow heat treatments or high temperature exposure of the anodic oxide without thermally induced crazing. A second phase of higher thermal expansivity than that of the oxide material is incorporated into the pores of the oxide in sufficient quantity to raise the coating's thermal expansion coefficient. The difference in thermal expansion between the anodic oxide coating and underlying metal substrate is reduced to a level such that thermal exposure is insufficient for any cracking to result. The second phase may be an electrodeposited metal, or an electrophoretically deposited polymer. The second phase may be uniformly deposited to a certain depth, or may be deposited at varying amounts among the pores.
摘要翻译：公开了一种用于最小化多孔阳极氧化物涂层与其相应的衬底金属之间的热膨胀差的方法，以便允许阳极氧化物的热处理或高温暴露而没有热诱导的裂纹。比氧化物材料高的热膨胀性的第二阶段以足够的量掺入到氧化物的孔中以提高涂层的热膨胀系数。阳极氧化物涂层和下面的金属基底之间的热膨胀差减小到使热暴露不足以导致任何开裂的程度。第二相可以是电沉积金属或电泳沉积的聚合物。第二相可以均匀地沉积到一定深度，或者可以在孔之间以不同的量沉积。
