A plasma spray process used for coating surfaces of a variety of components made of a plastic substrate. Powder particles are injected into a plasma jet where they soften and then strike the surface at high velocity to produce a strongly adherent coating. The component or work piece the coating is being applied to remains cool because the plasma is localized at the plasma gun. The plasma spray process allows for the melting of glass particles, creating a transfer mechanism to the plastic substrate. Components having complex shapes can be coated, without the issues currently encountered in dip coating. The powder coating is applied via plasma spraying, as a protective layer, giving glass like surface properties to a component having complex molded or formed shapes.

Since all methods of applying a drug liquid to a tip portion of a microneedle are application of the drug liquid in an open system, evaporation of the solvent from the drug liquid is unavoidable, such that the concentration of the drug liquid changes easily, and a large amount of the drug liquid is necessary. The invention provides a method of applying a drug to a pin-frog-shaped microneedle by using a small amount of the solution and without variation of the concentration of the drug liquid. A member having plural grooves is produced, and one end thereof is immersed in a drug liquid tank to fill the grooves with the drug liquid. The drug can be uniformly applied to a tip portion of the microneedle by setting the pin-frog-shaped microneedle to pass through the drug liquid in the grooves.

A degradable polymeric nanotube (NT) dispersant comprises a multiplicity of NT associative groups that are connected to a polymer backbone by a linking group where there are cleavable groups within the polymer backbone and/or the linking groups such that on a directed change of conditions, bond breaking of the cleavable groups results in residues from the degradable polymeric NT dispersant in a manner where the associative groups are uncoupled from other associative groups, rendering the associative groups monomelic in nature. The degradable polymeric nanotube (NT) dispersant can be combined with carbon NTs to form a NT dispersion that can be deposited to form a NT film, or other structure, by air brushing, electrostatic spraying, ultrasonic spraying, ink-jet printing, roll-to-roll coating, or dip coating. The deposition can render a NT film that is of a uniform thickness or is patterned with various thicknesses. Upon deposition of the film, the degradable polymeric nanotube (NT) dispersant can be cleaved and the cleavage residues removed from the film to yield a film where contact between NTs is unencumbered by dispersants, resulting in highly conductive NT films.

Components with improved erosion resistance are disclosed. A surface of the component or a substrate of the component is modified by coating the substrate with an elastomer layer. The elastomer layer is then modified by embedding hard particles onto an outer side of the elastomer layer. The hard particles exhibit higher fractured toughness providing enhanced erosion protection. The elastic properties of the elastomer experience little reduction because the surface embedded particles are located only at the outer side or outer surface of the elastomer layer. Therefore, the bond between the inner side of the elastomer layer and the substrate or component surface is not interfered with and the potential for electro-chemical corrosion and poor adhesion are not increased by the presence of the hard particles as the hard particles are located away from the inner face between the elastomer layer and the substrate. 1.
