The cylinder rod of a hydraulic cylinder includes a body portion having a bar shape, and a head portion arranged at a longitudinal end of the body portion. The body portion has a coating formed on its outer peripheral surface. The coating includes, in terms of area ratio in cross section, not less than 56.1% and not more than 84.4% of a chromium carbide phase, with the remainder consisting of a nickel-based alloy phase and an oxide phase. The area ratio of the chromium carbide phase may be 61.7% or more.

A motor comprises a stator comprising at least one core; a coil wound on the at least one core of the stator; a rotor having a rotor pole and being rotatably mounted relative to the stator; and at least one magnet disposed between the rotor and the stator. The at least one core comprises a composite material defined by iron-containing particles having an alumina layer disposed thereon.

A three-dimensional shaping apparatus includes a plasticizing portion plasticizing a material to generate a shaping material, a nozzle having a discharge port discharging the shaping material toward a table, a movement mechanism changing a relative position between the nozzle and the table, a discharge control mechanism provided in a flow path which connects the plasticizing portion to the nozzle and controlling a discharge amount of the shaping material from the nozzle, and a control portion controlling the plasticizing portion, the movement mechanism, and the discharge control mechanism to shape the three-dimensional shaping object. The control portion controls the discharge control mechanism so that when a relative movement speed between the nozzle and the table is a first speed, the discharge amount of the shaping material is set to a first discharge amount, and when the relative movement speed between the nozzle and the table is a second speed which is slower than the first speed, the discharge amount of the shaping material is set to a second discharge amount which is smaller than the first discharge amount.

A method and device for laser cladding by independently heating the cladding material and the surface of the workpiece consist in formation of the series of parallel annular laser beams, possibly different wavelengths, with an adjustable distribution of laser radiation power across the annular beams. The annular beams are transformed into a series of conical beams which are separately focused along a single optical axis, along which the cladding material is fed. The device can be supplemented with a cylindrical mirror for the multipass laser radiation through the stream of cladding material with the possibility of the laser radiation return to the laser resonator.

A blade outer airseal has a body comprising: an inner diameter (ID) surface; an outer diameter (OD) surface; a leading end; and a trailing end. The airseal body has a metallic substrate and a coating system atop the substrate along at least a portion of the inner diameter surface. At least over a first area of the inner diameter surface, the coating system comprises an abradable layer comprising a metallic matrix and a solid lubricant; and the metallic matrix comprises, by weight, ≧35% nickel, 12.0-20.0% cobalt, 5.0-15.0% aluminum, and 5.0-15.0% chromium.

A method and an apparatus for additive casting of parts is disclosed. The method may include: depositing, on a build table, a first portion of a mold, such that, the depositing may be performed layer by layer; pouring liquid substance into the first portion of the mold to form a first casted layer; solidifying at least a portion of the first casted layer; depositing a second portion of the mold, on top of the first portion of the mold; pouring the liquid substance into the second portion of the mold to form a second casted layer, on top of at least a portion of the first casted layer; and solidifying at least a portion of the second casted layer. The method may further include joining the first and second casted layers prior to the pouring of a third casted layer.
