The present invention addresses the problem of providing a sintered alloy valve guide capable of inhibiting valve adhesion even in a high-temperature environment. The problem can be solved by a sintered alloy valve guide impregnated with a lubricating oil including pores that are sealed on the valve guide outer circumferential surface. More particularly, the problem is solved by the sealing step of performing a sealing treatment of pores on the outer circumferential surface of a sintered body impregnated with a lubricating oil.

The invention relates to a method for the electrochemical polishing of metal surfaces by means of repeating pulse sequences, wherein at least one anodic pulse is provided, the current intensity of which rises continuously in the time curve up to a specifiable value. The invention further relates to the use of said method for components produced in 3-D and to a system therefor.

A method of forming a projectile for use in a firearm ammunition cartridge, the method including mixing a first material and a second material having different densities to produce a core mixture, disposing the core mixture in a die, heating the core mixture to the melting point, removing the core mixture from the die, quenching the core mixture, and plating the core mixture with a jacket material.

Techniques are disclosed for fabricating multi-part assemblies. In particular, by forming release layers between features such as bearings or gear teeth, complex mechanical assemblies can be fabricated in a single additive manufacturing process.

An inductor includes an element containing a magnetic metal powder and a resin, a coil that includes a winding portion and paired extended portions extended from both ends of the winding portion and that is embedded in the element, a pair of an external terminal electrically connected to one of the extended portions and an external terminal electrically connected to the other of the extended portions, and a conductive layer disposed on a surface of the element that crosses the winding axis of the coil. The conductive layer includes a first metal layer formed by fusing together the magnetic metal powder near the surface of the element and a second metal layer formed by plating on the first metal layer. The electrical resistivity of the second metal layer is lower than the electrical resistivity of the first metal layer.
