BLACK SUB-ANODIZED MARKING USING PICOSECOND BURSTS
A method includes generating a plurality of pulse bursts with a predetermined quantity of intra-burst pulses in each pulse burst and a temporal spacing between the intra-burst pulses, and with a pulse burst frequency, and scanning the pulse bursts across an anodized target at a scan rate so that the pulse bursts overlap at the anodized target by an amount that is above an overlap damage threshold and the intra-burst pulses provide a peak power and peak fluence that are below an ablation threshold of the anodized target so as to produce a laser mark on the anodized target with an L value of less than or equal to 30 and without a damage to an anodized layer of the anodized target.
Protection cover for a spray nozzle during a hardfacing process
A protection cover suitable for being placed between a spray nozzle and a metal part during a process of resurfacing the metal part, the protection cover including a side wall extending along a reference axis, the side wall including an inner surface and an outer surface, the side wall having a lower end and an upper end, the side wall being perforated by at least one lateral gas inlet port, the lower end of the side wall being perforated by a notch into which a portion of the metal part can be inserted, the upper end of the side wall being provided with an opening into which a portion of the spray nozzle can be inserted. The inner surface of the side wall includes at least one frustoconical portion.
Wear-resistant roller
The invention relates to a wear-resistant roller for crushing of particulate material, such as crude ore for use in the cement or minerals industry comprising a roller body, a wear surface on the roller body. The wear surface comprises welding beads comprising a primary fraction of carbide material and a secondary fraction of material selected from the group consisting of Nickel, Nickel alloys, mixtures of Nickel and Nickel alloys and mixtures of Nickel containing refractory hard materials, Cobalt, Cobalt alloys, mixtures of Cobalt and Cobalt alloys and mixtures of Cobalt containing refractory hard materials. Furthermore, the welding beads are welded to the roller body in an overlapping manner such that two neighbouring welding beads comprise an overlapping volume and a non-overlapping volume, the overlapping volume being an intersection volume between the two neighbouring overlapping welding beads, and the fraction of carbide material being higher in the overlapping volume than in the non-overlapping volume such that the overlapping volume has a higher wear resistance compared to the non-overlapping volume having a lower wear-resistance. Also the invention relates to a method of forming such a wear surface on a roller body.
Method for pre-treating stainless steel substrates before soldering using nanocrystalline solder foils
A soldered product comprising a first component soldered to a second component is provided. The first component comprises a stainless steel substrate, an adhesion promoter layer made of nickel deposited on at least one joining surface of the stainless steel substrate; and a tin layer deposited on the adhesion promoter layer. The tin layer has a layer thickness in the range of 10-30 m. The second component is typically a rare earth magnet.

THIN PLATE BONDING METHOD AND THIN PLATE ASSEMBLY
The present invention relates to a thin plate bonding method or a thin plate assembly, and more particularly, to a thin plate bonding method which includes coating with a coating material after increasing a surface roughness or increasing a surface roughness through coating with a coating material, and then, conducting diffusion bonding, such that excellent bonding strength is achieved even when the diffusion bonding is performed at low temperature and low pressure, thin plate deformation by thermal stress may be prevented, and high air tightness may be obtained since the coating material fills micro-pores.
PRODUCTS WITH A PATTERNED LIGHT-TRANSMISSIVE PORTION
A panel with an optically transmissive portion includes a group of holes drilled from one surface to another surface and filled with an optically transmissive material. The group of holes forms a pattern. The holes on a first surface form a smooth and continuous appearance to the naked eye. The holes on the other, second surface are sized so that a light source directed to the second surface illuminates the pattern to be visible to a viewer viewing the first surface. The panel may form a portion of a housing that houses the light source.
METALLIZING POLYMERS, CERAMICS AND COMPOSITES FOR ATTACHMENT STRUCTURES
A method of manufacture includes forming a metallized tie layer on a surface of a non-metallic component, positioning the surface of the non-metallic component to mate with a metallic surface of a second component, and joining the metallized tie layer with the mated metallic surface of the second component using metal to metal joining techniques.
METHOD FOR HEATING A METAL MEMBER, METHOD FOR BONDING HEATED METAL MEMBERS, AND APPARATUS FOR HEATING A METAL MEMBER
A heating method includes an oxide film forming step and a heating step. The thickness of an oxide film is set in a first range that includes a first maximal thickness and a second maximal thickness and that is smaller than a second minimal thickness in the relationship with the laser absorption having a periodic profile. The first maximal thickness corresponds to a first maximal value a of the laser absorption. The second maximal thickness corresponds to a second maximal value of the laser absorption. The second minimal thickness corresponds to a second minimal value of the laser absorption, namely the minimal value of the laser absorption that appears between the second maximal value and a third maximal value, or the maximal value of the laser absorption that appears subsequent to the second maximal value.
METHOD FOR PRESERVING A MARK ON A METALLIC WORKPIECE
The present invention relates to a method for preserving a mark on a metallic workpiece prior to a chemical etching process to remove a surface material from a surface of the workpiece carrying the mark, the method comprising the steps of: deepening the mark relative to the surface to form a first depth; and depositing a filling material into the first depth, wherein the filling material is adapted to be removed during the chemical process, such that a second depth is obtained at the mark after the chemical process. The present invention also relates to a method of treating a metallic workpiece to preserve a mark on the surface of the workpiece, the method comprising the step of treating at least a portion of the surface of the workpiece surrounding the mark to remove at least a surface oxide layer from the mark, the treating step being arranged such that it does not remove all of the surface material from said portion of the surface of the workpiece, but removes at least the surface oxide layer from the mark.
