When a friction stir weld tool penetrates the interface of two workpieces of dissimilar metal alloy materials, the resultant weld of the different alloy materials may produce a weak weld joint. Such weak joints are often experienced, for example, when attempting to form spot welds or other friction stir welds between a magnesium alloy sheet or strip and an aluminum alloy sheet or strip. It is discovered that suitable coating compositions placed at the interface of assembled workpieces can alter the composition of the friction stir weld material and strengthen the resulting bond. In the example of friction stir welds between magnesium alloy and aluminum alloy workpieces, it is found that combinations of copper, tin, and zinc, and other powders can strengthen the magnesium-containing and aluminum-containing friction stir weld material.

A synergistic composition and method is provided for controlling odor from waste products. The composition comprises a combination of magnesium hydroxide and a sulfide-consuming compound. The method includes adding a sufficient amount of the composition to a waste stream to provide sufficient sulfide-consuming compound to effect immediate removal of sulfide. The composition incorporates a pH elevating and buffering compound, which both increases and buffers the pH. The increased pH serves to reduce both the volatile sulfide species and the volatile fatty acid (VFAs) species. The elevated pH also promotes the growth of naturally occurring bacteria which metabolize the sulfide to an innocuous form. Finally, addition of the composition drives the pH into a range where the growth of sulfide producing bacteria is inhibited. The mixture has surprisingly been found to be synergistic with respect to both control of chemical species that produce odors and corrosion of metals commonly found in sludge dewatering equipment.

Vacuum carburizing of ferrous workpieces is performed at low pressure in a vacuum furnace using a napthene hydrocarbon as the carburizing medium. The furnace is constructed to be generally transparent to the napthene so that cracking tends to occur at the workpiece which functions as a catalyst to minimize carbon deposits. The napthene is supplied in liquid form to fuel injectors which inject the liquid napthene as a vapor at duty cycles and firing orders to produce a uniform dispersion of the hydrocarbon gas about the work resulting in uniform carburizing of the workpieces. An in-situ methane infrared sensor controls the process. Hydrogen is added to the napthene to either assure full carbon potential and produce methane or to perform variable carburizing.

Vacuum carburizing of ferrous workpieces is performed at low pressure in a vacuum furnace using an unsaturated aromatic such as benzene as the carburizing medium. The unsaturated aromatic is gas phase hydrogenated into a napthenes, such as cyclohexane, which is metered into the furnace chamber proper and functions as the carburizing gas. The furnace is constructed to be generally transparent to the napthenes so that cracking tends to occur at the workpiece which functions as a catalyst to minimize carbon deposits. The unsaturated aromatic is supplied in liquid form to fuel injectors which inject the liquid aromatic as a vapor at duty cycles and firing orders to produce a uniform dispersion of the hydrocarbon gas about the work resulting in uniform carburizing of the workpieces. An in-situ methane infrared sensor controls the process. Excess hydrogen beyond what is required to hydrogenate the aromatic is added to the furnace chamber to either assure full carbon potential and produce methane or to perform variable carburizing. Hydrogenation occurs in a hydrogenation coil in fluid communication with the furnace chamber with temperature for the reaction set by the position of the hydrogenation coil in the furnace insulation.

Disclosed is a shoe including a sole and an upper, wherein the upper includes an inner upper and an outer upper, wherein the inner upper includes 90% or more of a wool fiber and the outer upper includes a combination of 50 to 80% by weight of the wool fiber and 20 to 50% by weight of a synthetic fiber, based on the total weight of the outer upper.The shoe according to the present invention can facilitate discharge of sweat generated during exercise through the upper made of natural wool fiber and thus offer fresh wear sensation and can be worn without socks. In addition, elasticity of wool fabric can reduce resistance of shoes depending on shape change of feet during exercise or in a daily life, thus impairing foot comfort. As a result, people whose feet swell readily, such as pregnant women, can wear the shoes without irritation. Furthermore, the shoes according to the present invention are suitable for diabetic patients whose feet need to be protected from injury because they are made of wool which is a soft elastic fiber.

A film forming method forms a coating film on a workpiece (e.g., a cylinder head) having a film-deposited portion (e.g., an annular valve seat part) by moving a nozzle of a cold spray device relative to the workpiece along a film formation trajectory having a film formation starting point and a film formation finishing point in which the film-deposited portion overlaps to form an overlapping portion. The coating film is formed by causing a raw material powder to collide in a solid-phase state with the workpiece and plastically deform. Also, the coating film on the film-deposited portion is further formed such that an inclination angle of an end part of the coating film relative to a surface of the film-deposited portion is 45° or less at the film formation starting point of the overlapping portion.
