    摘要： A modified alkaline peroxide pre-bond process for the surface treatment of titanium is useful as a practical production process. In this modified process, an exceptionally wide range of allowable peroxide concentration, namely, from 0.001 molar to 0.2 molar (and preferably 0.001 molar to 0.01 molar) may be tolerated and a novel real-time peroxide monitoring and control technique is employed. The process is further improved by means of the use of stabilizers such as precipitated magnesium silicate which greatly increases bath life-time and reduces the overall operating cost of the process. Solution operating conditions have been defined which permit titanium adherends to be processed satisfactorily over a wide range of hydrogen peroxide concentration. In particular, the acceptable temperature range is 125.degree. F.-165.degree. F. (51.7.degree. C.-73.8.degree. C.); the treatment period is 15 to 25 minutes and the hydroxide concentration is 0.3 to 0.9 molar. The preferred values are approximately 145.degree. F. (62.7.degree. C.); 20 minutes, and 0.5 molar, respectively. An electrochemical method has been established utilizing a magnesium electrode (114) which provides a stable potential characteristic that is dependent only on the concentration of the peroxide. The resultant capability to reliably monitor the peroxide concentration in real time in turn permits an automated feed system to be effectively utilized for sustaining the peroxide concentration within the desired limits.

    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.
