✦ Synopsis

is a new sintered alpha silicon carbide material designed for optimum performance in sliding contact applications such as pump seal faces and product lubricated bearings. Carborundum says this material improves upon the corrosion and erosion resistance properties of sintered alpha Sic through the addition of spherical pores.

These pores are discrete, non-interconnecting and dispersed in a controlled manner throughout the body of the material. The spherical pores act as fluid or lubricant reservoirs helping to promote the retention of a fluid film at the interface of sliding component surfaces.

According to the maker, this "pore" based lubrication mechanism allows Hexoloy SP Sic to outperform conventional reaction-bonded and sintered silicon carbides in a wide variety of severe seal and bearing applications.

The geometry of a bird's lifting surfaces (wings and tail) varies during flight. The wing span, wing area, tail spread, and tail angle of attack can all change substantially during a single wingbeat, there is systematic variation in geometry with flight speed, and the geometry adopted during manoeuv
