摘要： Disclosed is a zirconium alloy material having high corrosion resistance regardless of thermal history during its manufacturing process. The zirconium alloy material is obtained by providing a zirconium alloy containing on the mass basis: 0.001% to 1.9% of Sn, 0.01% to 0.3% of Fe, 0.01% to 0.3% of Cr, 0.001% to 0.3% of Ni, 0.001% to 3.0% of Nb, 0.027% or less of C, 0.025% or less of N, 4.5% or less of Hf and 0.16% or less of O with the remainder being inevitable impurities and zirconium, being formed of a bulk alloy and a surface layer, in which the surface layer has a plastic strain of 3 or more or a Vickers hardness of 260 HV or more and an arithmetic mean surface roughness Ra of 0.2 μm or less.

摘要： A linear solenoid includes a plunger to slide in an axis direction, and a stator core. The plunger includes a magnetic base, and a nonmagnetic plating layer defined on the magnetic base. The stator core has a first blocker arranged between a first magnetic core and a second magnetic core. The second magnetic core has a second blocker distanced from the first blocker in the axis direction. Each of the blockers limits a magnetic reaction. The plunger directly slides on an inner circumference face of the stator core at only two sections corresponding to the first and second blockers.

摘要： A plunger is axially intersectable with a tubular recessed portion formed in a magnetically attracting core of a stator core upon slide movement of the plunger, which places a predetermined portion of the plunger into the tubular recessed portion. A magnetic material in the predetermined portion of the plunger may have a predetermined outer diameter that is smaller than an outer diameter of the magnetic material in a slidably contacting portion of the plunger, which slidably contacts a slidable core of the stator core. Alternatively, a magnetic material in the tubular recessed portion may have a predetermined inner diameter that is larger than an inner diameter of the magnetic material in a slidably contacting portion of the slidable core, which slidably contacts the plunger.
