Wear behaviour of AA6061 aluminium alloy and its composites

A compacted powdered iron core utilizes iron powder in the 0.002 to 0.006 mean particle size range which is first coated with an alkali metal silicate and then overcoated with a silicone resin polymer. The treated powder is compressed to approximately 94% of theoretical density and then annealed at approximately 600° C. This results in a core component characterized by overall core losses as low as in conventional laminated cores in A.C. operation.

Powdered iron core magnetic devices

Disclosed is an magnetic core comprising a molded product made of an iron powder and/or an iron alloy magnetic powder having a mean particle size of 10 to 100 μm, and 1.5 to 40%, as a total amount in terms of volume ratio, of an insulating binder resin and an insulating inorganic compound powder. Also disclosed is a useful method of producing the magnetic core.

Magnetic core and method of producing the same

A compressed powder core is made of a compressed body of a magnetic powder each particle of which has a surface covered with an insulating layer. The insulating layer is formed of an insulating material selected from the group consisting of an inorganic compound powder having an electronegativity of not less than 12.5, an inorganic compound powder having an electronegativity of less than 8.5, a metal alkoxide and a decomposition product of a metal alkoxide.

Mechanical Properties and Wear Resistance of 6061 Alloy Reinforced with a Hybrid of Al2O3 Fibers and SiC Whiskers

The tensile properties and wear resistance of SiC whisker-reinforced Al alloy 4032 composites were investigated. The elastic modulus of T 6 heat treated SiC/4032 composites can be expressed as E(GPa) = 180Vf(vol pct) + 85. The wear loss of SiC/4032 composites decreases rapidly with an increase in the volume fraction of SiC whisker up to 14 percent, beyond which it remains unchanged. The addition of BN gives rise to the degradation of the mechanical properties and of the coefficient of friction, which improves the wear resistance of the composites. The wear resistance of SiC/4032 composites depends remarkably on the size and distribution of Si particles in the Al alloy 4032 matrix. 20 references.
