Tantalum Alloy Has Improved Resistance to Corrosion and Hydrogen Embrittlement H.C. Starck has developed a new tantalum alloy with improved corrosion and hydrogen embrittlement resistance. Ultra76 tantalum has significantly lower corrosion and hydrogen embrittlement rates than NRC76 with comparable mechanical properties. Ultra76 exhibits hydrogen embrittlement rates 10 to 1009 lower than those of NRC76, with or without platinum spots in HCl environments outside currently acceptable ranges of concentration and temperature. Additionally, in aggressive H2SO4 solutions at temperatures 30 to 50 C above currently acceptable ranges, Ultra76 had hydrogen embrittlement rates that were 5 to 109 lower than NRC76, also with or without platinum spots. A free brochure, ‘‘Ultra 76 Tantalum for Corrosive Resistant Applications,’’ is available for download from the company website. For more information: H.C.

Airless Tire Successfully Tested New Tech Tire, Boca Raton, Fla., a division of Scitech Industries, a Delaware corporation, has successfully tested the nonpneumatic New Tech Tire Airless Tire at an industry laboratory in Ohio. The tire achieved a cool and uniform 10-h run at highway speed at passenger car load. The tire is self-supporting, with internal glass fiber composite ribs supporting the load. It was built and cured in a conventional steam-bladder mold at a commercial tire factory and mounted on a standard rim with a conventional

tire mounting machine. The composite rib and tire construction are covered by worldwide patents. Some of the benefits this tire could provide to the manufacture and consumer are: • • •
• • •
Punctures will not flatten tire, and tire can be retreaded. Weight is equal to that of pneumatic tires. Tire requires only three rubber compounds, is manufactured on standard equipment, and mounts on standard rims. Better fuel economy, as much as 2% or more. Quicker vehicle handling due to no sidewall warpage. Weight and cost savings due to no spare, jack, or tools.

Condition Monitoring System Maximizes Hydraulic Hose Life LifeSense hose is a patented hydraulic hose condition monitoring system from Eaton Corporation. Developed in conjunction with Purdue University and the Purdue Research Foundation’s Office of Technology Commercialization, the system continuously monitors the health of high-pressure hose assemblies in hydraulic systems and alert users when an assembly approaches the end of its useful life. A single monitoring unit can handle input from multiple hose assemblies. ‘‘Most hydraulic maintenance programs are designed to avoid hose failures by replacing assemblies at regular
