Problems solved by technology

[0015] In all of the prior art examples above, as well as common prior art, the persistent problem is to provide moderate but not excessive lubrication to a wide variety of components with varying geometries, surface qualities and characteristics
When worn or punctured, the overall apparent coefficient of friction of the sliding surface changes, causing problems with friction changes; where the lubricating layer is completely worn, the underlying layer will also be damaged , which can lead to detrimental effects such as increased likelihood of corrosion over the lifetime of the substrate

Embodiment 1

[0168] The steel battery panels are stripped by 50% hydrochloric acid, rinsed with deionized water, and then in a cyanide-free alkaline zinc dipping solution with a current density of 20 amperes per square inch (ASF) (2.15A / dm 2 ) to achieve a coating thickness of 8 to 10 microns.

[0169] The first panel was immersed in solution A (passivator) for 60 seconds to form a conversion coating, followed by immersion in solution B (corrosion-resistant sealing material) for 60 seconds. This plate is equivalent to applying a layer of sealing resin directly to the conversion film.

[0170] Immerse the second panel in solution A for 60 seconds to form a conversion film, then add 2ml / LFUCHS Immerse in solution B of Gleitmo 605 for 60 seconds. This plate is equivalent to applying a conventional integral lubricating seal coat to the conversion coating.

[0171] The third panel was immersed in the mixture of solution A in which 2.5ml / L Michelman ME 93235 emulsified lubricant had been ad...

Embodiment 2

[0174] 25 unplated bolts in each six-bolt geometry:

[0175] Captive washer bolts from Brogola, part number W701605, model number M8×1.25×25 8.8PC;

[0176] Confinement flange face bolts from SPS Technology, part number N606543, model M8×1.25×309.8PC;

[0177] Flange bolts from Indiana Auto., part number N605790, model M89.8PC;

[0178] Flange bolts from Textron Group, type M10×45 10.9PC;

[0179] Hex head bolts from Wilson Garner, model M10×40 9.8PC; and

[0180] Flange face bolts, type M10×65 8.8PC from Freiburg, Baden, assembled into 18×10 inch plating drums, cleaned, then electroplated with an acidic galvanizing solution to deposit zinc to a thickness of 10 microns layer.

[0181] The bolts were then separated into five groups of five bolts each with a six-bolt geometry, and each group was then subjected to torque tension testing on a Ford WZ 100 equipped with an RS Technologies torque tension device All were processed in one of five different post plate programs.

Embodiment 3

[0190] In this example, each 40 M8 9.8PC flange bolt from Indiana Automotive Fasteners, part number N605790, was electroplated in zinc conversion coating by dipping in the following solutions prepared by: Heating to 60°C and standing for 24 hours, then cooling to 130°C for use.

[0191] CrCl 3 50g / l

[0192] Co(NO 3 ) 2 3g / l

[0193] NaNO 3 100g / l

[0194] Oxalic acid 30g / l

[0195] Malonic acid 60g / l

[0196] After the conversion coating is formed, the parts are divided into two groups.

[0197] The first control group was repeatedly immersed in 30ml FUCHS Gleitmo 605 in solution B, and then air spin dried at 82°C for 15 minutes to obtain the desired thickness of the integral seal coat.

[0198] The second group was treated according to one embodiment of the present invention by successively immersing them in solutions containing solution B and 240ml FUCHS respectively. Gleitmo 605, solution B and 120ml FUCHS Gleitmo605, solution B a...

Abstract

A coated substrate and a process for forming the coated substrate, including a first lubricious coating layer overlying the substrate, the first lubricious coating layer including a first lubricant providing to the first lubricious coating layer a first coefficient of friction; and a second lubricious coating layer overlying the first lubricious coating layer, the second lubricious coating layer including a second lubricant providing to the second lubricious coating layer a second coefficient of friction, in which the second coefficient of friction is greater than the first coefficient of friction.

Description

technical field [0001] The present invention relates generally to lubricious coatings for products, and more particularly to lubricious coatings for products such as fasteners, automotive parts, and the like, and to methods of making these coatings and applications of these coatings. layer product. Background technique [0002] Coatings for protecting and improving the surface quality of products such as plastic or metal (ie, solid) fasteners and other assembly items have gained widespread interest and acceptance, particularly in the automotive industry where stringent requirements prevail. Among the requirements is a surface that exhibits a low and uniform coefficient of friction, includes coatings that adhere tightly to the substrate and includes additives for purposes such as corrosion prevention and staining. Many coatings and their treatments have been developed and used for the above purposes, and many of these coatings are still of great importance today. However, e...
