The method manufactures a hermetic sealing lid member used for an electronic component housing package including an electronic component arrangement member on which an electronic component is arranged. The method includes forming a clad material in which a silver brazing layer that contains Ag and Cu and a first Fe layer arranged on the silver brazing layer and made of Fe or an Fe alloy are bonded to each other by roll-bonding a silver brazing plate that contains Ag and Cu and a first Fe plate made of Fe or an Fe alloy to each other and performing first heat treatment for diffusion annealing; softening the clad material by performing second heat treatment; and forming the hermetic sealing lid member in a box shape including a recess portion by bending the softened clad material.

An electrolyte solution for iron-tungsten plating is prepared by dissolving in an aqueous medium a divalent iron salt (e.g., iron (II) sulfate) and an alkali metal citrate (e.g., sodium citrate, potassium citrate, or other alkali metal citrate) to form a first solution, dissolving in the first solution a tungstate salt (e.g., sodium tungstate, potassium tungstate, or other potassium tungstate) to form a second solution, and dissolving in the second solution a citric acid to form the electrolyte solution. An iron-tungsten coating is formed on a substrate using the electrolyte solution by passing a current between a cathode and an anode through the electrolyte solution to deposit iron and tungsten on the substrate.

A welded assembly includes a first object or substrate, an interlayer, and a subsequent layer deposited on the interlayer. The interlayer is an ESD coating deposited on the first object, and the subsequent layer is deposited by ESD on the interlayer. The subsequent layer is made of a different materials from the substrate. Both the interlayer and the subsequent layer are subject to peening. In one case the interlayer has a lower either a lower thermal conductivity or a lower electrical conductivity than the substrate and the subsequent layer. In another example, the subsequent layer has a cermet content of greater than 40% by wt.

A steel wire having a flat shape in a cross-section perpendicular to a longitudinal direction, wherein an outer shape of the cross-section includes a first straight portion, a second straight portion arranged opposite to the first straight portion, and a first curved portion and a second curved portion that connect the first straight portion to the second straight portion, wherein the first curved portion is arranged opposite to the second curved portion, and wherein a ratio of W1 to W2 is 75% or less, where W1 is an average value of a length of the first straight portion and a length of the second straight portion, and W2 is a maximum distance between the first curved portion and the second curved portion.

A sliding member includes a back-metal layer including an Fe alloy and a sliding layer including a copper alloy including 0.5 to 12 mass % of Sn and the balance of Cu and inevitable impurities. A cross-sectional structure of the sliding layer includes first copper alloy grains in contact with a bonding surface and second copper alloy grains not in contact with the bonding surface. The first and second grains have an average grain size D1 and D2 respectively. D1 is 30 to 80 μm; and D1/D2=0.1 to 0.3. In the cross-sectional structure, the second grains includes third grains that includes internal grains therein that are not in contact with a grain boundary of the third grains. A total area S1 of the third grains and a total area of the second copper alloy grains S2 satisfy: S0/S2=0.25 to 0.80.

Discussed is a deposition mask including a metal plate having a first surface and a second surface opposite to the first surface, wherein the metal plate including an invar, wherein the metal plate includes a plurality of through-hole, wherein the through-hole includes a first surface hole forming in the first surface, a second surface hole forming in the second surface, and a connecting part through which the first surface hole and the second surface hole communicate with each other, and wherein an angle formed by a virtual line connecting the end of the connecting part and the end of the second surface hole, and a virtual line extending in a direction parallel to the second face from the end of the second surface hole is 30 to 60 degrees.
