    摘要: A method for improving the resistance to surface roughening of tungsten-containing metallic articles such as cutting tools and hot mill rolls made of a cemented carbide or high-speed steel and extending the lifetime thereof. The method comprises treating a metallic article with an aqueous alkaline solution containing calcium ions and optionally tungstate ions having a pH greater than 8 so as to form a coating of calcium tungstate on the surface of the metallic article. In hot rolling with tungsten-containing rolls, the aqueous solution can be used as at least part of a cooling water to cool the rolls, thereby extending the period before roll replacement becomes necessary due to surface roughening and decreasing the frequency of roll dressing required during hot rolling.

    摘要: A method for forming an oxidized chromium film on the surface of chromium metal in a controlled manner which involves the use of a permanganate solution. The chromium metal film is first subjected to a basic hydrogen peroxide solution. The chromium surface is then removed from the hydrogen peroxide solution and immersed in an aqueous permanganate solution maintained at a temperature less than about 100.degree. C. for a time preferably within 1 to 5 minutes. At this time the chromium film has been oxidized to the desired thickness depending upon the time and temperature at which the surface has been subjected to the solutions. The surface is removed from the permanganate solution and dried. Should additional thickness of chromium oxide films be desired, the surface is intermittently subjected to the permanganate solution and dried to build up the desired thickness of chromium oxide.

    摘要: This invention provides color development methods of metallic titanium used for manufacture of black titanium or titanium tinted in other chromatic colors. In one method, metallic titanium is treated with an alkali solution. It enables colored titanium rich in color variation with high efficiency, irrespective of the material configuration. The brightness of black is further reduced by conducting a nitriding process, after this process. In another method, the metallic titanium is oxidized after forming the titanium nitride film on its surface by nitriding it. Black titanium is produced with low brightness. In this way, colored titanium with various tones is produced. Moreover, the close adherence of the film with colors developed thereon is enhanced.
