Self Lubricating Composites

This chapter illustrates the effect of the addition of solid lubricants on the high temperature friction and wear behavior of Ni-based composites. Ni-based composites containing solid lubricant particles both in nano and micrometer range have been fabricated through powder metallurgy route. In order to explore the possible synergetic action of a combination of low and high temperature solid lubricant, nano or micro powders of two or more solid lubricants were added in the composites. This chapter introduces the fabrication of the Ni-based self-lubricating composites containing graphite and/or MoS2, Ag and/or rare earth, Ag and/or hBN as solid lubricants and their friction and wear behavior at room and elevated temperatures. The chapter also includes information on some lubricating composite coatings such as electro-deposited nickel-base coating containing graphite, MoS2, or BN and graphene and their tribological characteristics.

To meet the requirements of integrative mechanical properties and shielding effectiveness of nuclear radiations shielding materials, the boron-rich shielding coating (Fe67.5Ni23.5B9, in wt. %) were produced onto 321 stainless steel substrate (SS) by the air-plasma spraying technology. This type of coating-SS laminated composite will be likely to be used as protection against neutrons and γ rays from radiation shielding systems. The microstructure was characterized by scanning electron microscope (SEM), energy-dispersive spectrometry (EDS) and X-rays diffraction (XRD). The mechanical properties of Fe67.5Ni23.5B9 coatings were investigated, including adhesion strength, tensile properties and residual stress. The shielding effectiveness of the coating-SS laminated composite, including the slowing down of fast-speed neutrons, absorption for 0.4ev below thermal neutrons and the attenuation against 60Co and 137Cs γ rays were investigated. The results show that the produced Fe67.5Ni23.5B9 coatings-SS laminated composite possess homogeneous microstructure, satisfactory integrative mechanical properties and shielding effectiveness which testify the possible application in radiation shielding systems.

Nanocrystalline Composite

The Fe-based amorphous coatings were prepared by Air plasma thermal spraying. X-ray diffraction results show that the coating fabricated at current of 300A has an amorphous structure. The amorphous nanocrystalline composite coatings were obtained at current more than 300A. The friction and wear properties of the coatings were investigated in Ml-10 friction and wear tester at dry friction condition. The results show that the amorphous content is the main influencing factors to wear resistance of coating. The density of coating is another reason to affect the wear resistance of amorphous nanocrystalline composite coating.
