Abstract: A system and process for chemical milling or stripping a surface portion and/or surface deposit from metal products, such as chemically milling a metal to remove surface defects and/or stripping non-metallic deposits from a metal surface. The metal product is associated with an electrolyte, such as by being immersed in a tank filled with the electrolyte, such as a diluted acid mixture. A counter electrode having a higher potential than the metal of the metal product is also associated with the electrolyte. The counter electrode is dc coupled to the metal product, or to a conductive component in direct contact with the metal product, such that electric current flows from the metal to the counter electrode due to the difference in the natural potentials of the metal and the counter electrode. The surface portion or deposit is thereby stripped or milled from the metal product.

Abstract: A deposition process including applying an inoculant to at least a portion of the surface of a metal component, and then forming an intermetallic layer at the inoculant surface, such as by exposing at least the coated surface portion to a deposition environment.

Abstract: Medical devices, such as scalpels (10), needles (30) and electrosurgical knife tips (50), are provided with a silane coating (20) directly against the parent metal (16, 33, 63) of the tissue-contacting (15) distal ends (14, 37, 60) thereof whereby to impart advantageous non-stick and/or conductive properties thereto.

Abstract: A silane coating (32) is provided which affords non-stick properties to a metal surface (20, 22) of a cooking utensil (10) and which can be provided with colorant (42) to impart a stable color appearance, including white, to the utensil (10). An easy repair method is also described.

Abstract: A deposition process including applying an inoculant (50) to at least a portion (12a) of the surface (12) of a metal component (10), and then forming an intermetallic layer (60, 70, 100) at the inoculant surface (12), such as by exposing at least the coated surface portion (12a) to a deposition environment (26).

Abstract: A system and process for cleaning a hollow interior or a passageway of a metal member including an external container having counter electrode material with a higher potential than the metal member with the counter electrode material being dc coupled to the metal member, and electrolyte passing through the container to contact the counter electrode material and fluidicly coupled into the hollow interior or the passageway of the metal member to clean same.

Abstract: A system and process is provided for stripping metal oxide scale from metal products, such as stripping iron oxide scale from steel sheet and steel mill products. Steel having iron oxide scale compiling a layer of one or more iron oxide phases is associated with an electrolyte, such as by being immersed in a tank filled with the electrolyte, such as a dilute acid mixture. A counter electrode having a higher potential than steel is also associated with the electrolyte. The counter electrode is dc coupled to the steel, or to a conductive component in direct contact with the steel, such that electric current flows from the steel to the counter electrode due to the difference in the natural potentials of steel and the counter electrode. The metal oxide scale is thereby stripped from the steel.
