Disclosed are quaternary ammonium salts containing non-halogen anions such as carbonates, bicarbonates, phosphates, glycolates and mixtures thereof as conversion coatings or additives imparting anti-corrosive properties to paints. The invention relates to a method for inhibiting the corrosion of metal surfaces by applying a composition containing one or more quaternary ammonium carbonate or bicarbonate. The disclosure is also directed to anti-corrosive coatings for metal substrates containing these compounds and to metal substrates having these anticorrosive coatings.

A method for the manufacture of a hardened part coated with a phosphatable coating is provided. The method includes providing a steel sheet pre-coated with a metallic coating including from 4.0 to 20.0% by weight of zinc, from 1.0 to 3.5% by weight of silicon, optionally from 1.0 to 4.0% by weight of magnesium, and optionally additional elements chosen from Pb, Ni, Zr, or Hf, the content by weight of each additional element being less than 0.3% by weight, the balance being aluminum and unavoidable impurities and residuals elements. The steel sheet is cut to obtain a blank, the blank is thermally treated at a temperature between 840 and 950° C. to obtain a fully austenitic microstructure in the steel, the blank is transferred into a press tool and hot-formed to obtain a part. The part is cooled to obtain a martensitic or martensitic-bainitic microstructure or made of at least 75% of equiaxed ferrite, from 5 to 20% of martensite and bainite in amount less than or equal to 10%.

The invention discloses an agricultural equipment gearbox coating line which comprises a line feeding area, a washing area, a drying area, a paint spraying area, a levelling area, a finishing coat drying area, a line discharging area, a rail, a coating assembly line chain, a plurality of lifting appliance assemblies and a drive motor, wherein the line feeding area, the washing area, the drying area, the paint spraying area, the levelling area, the finishing coat drying area and the line discharging area are sequentially connected; the rail is fixedly arranged at the top of the entire agricultural equipment gearbox coating line; the coating assembly line chain is connected with the drive motor; the coating assembly line chain is connected with the rail; driven by the drive motor, the coating assembly line chain moves along the rail; the lifting appliance assemblies are fixed on the coating assembly line chain; and gearboxes are lifted through the lifting appliance assemblies at the line feeding area. The agricultural equipment gearbox coating line is reasonable in structure, light and convenient to operate, excellent in coating effect and high in paint adhesive force, and the agricultural equipment gearbox coating line and a coating method thereof can meet the using requirements.

An object of the present invention is to provide a golf ball excellent in fluidity, adhesion of the paint film, and repulsion. Another object of the present invention is to provide a golf ball which is excellent in durability and low-temperature durability. The present invention provides a golf ball comprising: a core and a cover covering the core, wherein the cover is formed from a cover composition that contains as a resin component, (a) a specific high melt viscosity ionomer resin being neutralized with at least two metal ions, and (b) a low melt viscosity ionomer resin being neutralized with at least two metal ions, in a ratio of (a) the high melt viscosity ionomer resin / (b) the low melt viscosity ionomer resin being 55 mass % to 99 mass % / 45 mass % to 1 mass %, wherein at least one of metal ions neutralizing carboxyl groups of (a) the high melt viscosity ionomer resin and / or (b) the low melt viscosity ionomer resin is a divalent metal ion and a content of the divalent metal ion per 100 g of the resin component is at least 0.020 mole.
