In this study, Al–Ti–Co was used to improve the surface performance of pure Ti. Laser cladding is an important surface modification technique, which can be used to improve the surface performance of pure Ti. Laser cladding of the Al–Ti–Co + TiB2 pre-placed powders on pure Ti can form...

The synthesis of hard composite coating on titanium alloy by laser cladding of Al/Fe/Ni+C/Si3N4 pre-placed powders has been investigated in detail. SEM result indicated that a composite coating with metallurgical joint to the substrate was formed. XRD result indicated that the composite coating...

Effect of the tempering on the microstructures and tribological properties of the laser alloying coatings is investigated. Laser alloying of the T-Co50/TiC mixed powders on a 45 steel substrate can form a hard composite coating, which increased the micro-hardness and wear resistance of the...

In situ synthesized TiC reinforced composite coating was fabricated by laser cladding of Al-Ni-Cr-C powders on titanium alloys, which can greatly improve the surface performance of the substrate. In this study, the Al-Ni-Cr-C laser-cladded composite coatings have been researched by means of...

Hyperbranched aliphatic polyester grafted silica nanoparticles (HAPE-SNs) have been prepared via the polycondensation of a AB2 monomer, 2, 2-bis(hydroxymethyl)propionic acid (bis-MPA) from the surface of the aminopropyl silica nanoparticles (APSNs) by a facile one-pot method catalyzed with...

The well-defined poly(hydroxyethyl acrylate) (PHEA) brushes were grafted from the surfaces of the activated carbon (AC) powder with the controlled/"living" radical polymerization technique. First, surface functional groups of the AC powder were homogenized to hydroxyl groups by oxidizing with...

The polyacrylamide surface grafted poly(vinyl chloride) (PAM-PVC) film was successfully prepared via a facile copper-mediated surface-initiated atom transfer radical polymerization (SI-ATRP) of acrylamide (AM) from the surfaces of the PVC thin film with their surface labile chlorines as...

The hyperbranched aliphatic polyester grafted activated carbon (HAPE-AC), was successfully prepared by the simple "one-pot" method. The surface functional groups of commercial activated carbon particles were homogenized to hydroxyl groups by being oxidized with nitric acid and then reduced with...
