In order to produce industrially advantageously an electroformed copper/niobium composite piping material wherein an electroformed copper layer and a niobium thin piping material are strongly bonded to each other, the electroformed copper/niobium composite piping material can be produced by coating any one or each of the outer peripheral surface and the inner peripheral surface of a niobium thin piping material with a nickel thin film, coating the surface of the nickel thin film with copper by electroforming, and subsequently annealing the resultant.

Copper/niobium composite piping material produced by copper electroforming, process for producing the same and superconducting acceleration cavity produced from the composite piping material

The objective of the present invention is to provide a product that is superior in barrier properties (for example, zinc erosion resistance and anti-adhesive property), abrasion resistant property, surface hardening property, thermal stability and life-time prolonging property. The product, which is made in direct contact with molten metal containing zinc in a molten state, is characterized by including an iron-tungsten alloy coating that is applied to a part or the whole of the surface of the product that comes directly in contact with the molten metal.

Product having improved zinc erosion resistance

A coater blade and backing roll combination contains a coater blade having an elastic steel blade with a wear-resistant coating formed thereon. The wear-resistant coating has a hardness greater than that of the elastic steel blade and is provided on an edge of the blade to define a coater surface for contacting with a moving surface of coated paper on the backing roll. The backing roll has a concave outer surface having a curvature corresponding to a quadratic equation and the coater surface has a concave curvature corresponding to the quadratic equation.

Coater blades and their manufacturing methods

A roll used for tensioning a canvas belt used to hold paper against a dryer. The roll includes a main cylindrical body formed of steel. A layer formed of a metal harder than steel is disposed over the outer surface of the main body. The metal layer is formed with a channel around its center so as to define two spaced roll end sections of a common diameter. A fluororesin layer is disposed in the metal layer channel and is shaped so as to have an outer surface of a diameter equal to that of the metal layer end sections.

Roll with composite coats

This invention relates to a production method of a mold for continuous casting comprising the steps of: providing a cooled water path in the mold water cooling mechanism; filling the cooled water path with a wax; making the wax surface uniform; providing a copper or copper alloy stratum on the wax surface by electrolytic plating; removing wax from the cooled water path and uniting the mold water cooling mechanism with the mold as one; and comprising the additional step of providing a copper or nickel plating on the surface on which is provided the cooled water path in the mold water cooling mechanism before depositing wax in the path.
