Abstract: A method of forming an alloy layer on the surface of a substrate comprising forming in a vessel a molten bath comprising at least one vaporizable alloying component having a higher vapor pressure than at least one other vaporizable alloying component in said bath, forming a thin, substantially inert, liquid layer of an evaporation retarding film on the upper surface of said molten bath, said liquid layer of an evaporation retarding film having a lower or comparable vapor pressure than both said vaporizable alloying component having a higher vapor pressure and said other vaporizable alloying component on said substrate, co-vaporizing at least a portion of both said vaporizable alloying component having a higher vapor pressure and said other vaporizable alloying component whereby said evaporation retarding film retards the initial evaporation of said vaporizable alloying component having a higher vapor pressure, and forming an alloy layer comprising both said vaporizable alloying component having a higher vapor

Abstract: A photoreceptor having improved flexibility and durability comprising a metal- or metal-coated substrate and an inorganic photoconductor layer in charge blocking contact with the substrate, the photoreceptor being obtained by initially bombarding a grounded or floating substrate with electrons and non-metallic high energy ions in the presence of oxygen and exposing the resulting clean oxide-coated substrate to a vapor cloud of photoconductor material bombarded by electrons and non-metallic ions to form high energy ions, the vapor cloud being initially obtained by evaporation from a crucible in a coated under glow discharge conditions; the latter functional step being optionally effected in combination with at least part of the initial bombardment step.

Abstract: A one-step process, method and corresponding xerographic photoreceptor obtained thereby, having all or part of the hole generating layer in the trigonal form, the process being effected and the photoreceptor obtained through the use of a glow discharge and ionizable inert gas.

Abstract: A durable photoreceptor having improved flexibility comprising a metal- or metal-coated flexible substrate and an inorganic photoconductor layer in charge blocking contact, the photoreceptor being obtained by initially bombarding the metal substrate, as cathode, with positive ions of an inert gas of low ionization potential under glow discharge in the presence of oxygen; and exposing the resulting oxide-coated substrate to a vapor cloud of photoconductor material consisting essentially of charged and uncharged material in an electrical field, utilizing the metal substrate as a cathode and a donor of said vapor cloud of photoconductor material or container thereof as an anode, the latter step being effected in combination with at least part of the initial bombardment step.

Abstract: A durable photoreceptor having improved flexibility comprising a metal- or metal-coated flexible substrate and an inorganic photoconductor layer in charge blocking contact, the photoreceptor being obtained by initially bombarding the metal substrate, as an electrode, with both negative and positive ions of a non-metallic gas of low ionization potential under AC glow discharge in the presence of oxygen; and exposing the resulting oxidized substrate to a vapor cloud of inorganic ambipolar photoconductive material consisting essentially of positively and negatively charged and uncharged photoconductive material in a low frequency AC electrical field, utilizing the substrate as one electrode, a source of said vapor cloud of photoconductive material or adjacent structure as the other electrode, the latter functional step being effected in combination with at least part of the initial bombardment step.
