    • A method for increasing the resistance to alkaline dissolution of a phosphate conversion coating on a corrodible metal substrate. The substrate is exposed to the phosphating solution by spraying or dipping to chemically effect a reaction with the substrate. The solution contains 84-94 molar percent of the total metal cations of a first layer-forming divalent metal cation, the metal cation having a hydroxide which has a lower solubility in an alkaline solution than iron or zinc hydroxide and is preferably selected from the group consisting of nickel, cobalt, magnesium and lanthanides, and a second layer-forming metal cation in the form of zinc present in an amount of .2-.6 g/l as a Zn . The molar ratio range of the first and second metal cations is in the range of 5.2:1 to 16:1, and the first metal cation is present in the solution in an amount of at least 1.0 g/l. The deposited coating has a first divalent metal cation present in an amount of at least 15 mole percent of the total divalent cations, and a second divalent cation present in an amount of at least 25 % by weight of the coating; the coating preferably has a uniform weight of less than 1.3 g/m (120 mg/ft ).

    • A high lubricity codeposit of zinc and graphite, and an improved method for depositing the codeposit. The coating is characterized by a coefficient of friction equal to or less than .130, and a high resistance to corrosion evidenced by no red rust in a salt spray environment for 72 hours and no destruction due to corrosion in an industrial environment, containing sulphur dioxide, for four months. When the codeposit additionally has a chromate outer coating, the system has a coefficient of friction equal to or less than .112 and has no red rust in a salt spray environment for at least 120 hours. The codeposit is applied by immersing a cleansed metallic substrate in an acidic zinc plating electrolyte containing at least 40 g/l zinc ions and 30-110 g/l insoluble bulk graphite, with a pH of 5-5.7. The cell of which the electrolyte is a part is energized to plate out a codeposit; the graphite is continuously agitated while in solution, the agitation being periodically interrupted to allow the graphite to settle and saturate the zinc interface as it is plating out.

    • A shock absorber (10) has a rebound stop assembly (22). The rebound stop assembly (22) rests upon a shoulder (30) fixed to a piston rod (16). The rebound stop assembly (22) includes an elastomeric ring (24) interposed between two collars (26 and 28) forming an annular chamber (74) therebetween. At the end of the rebound stroke of piston rod (16), the rebound stop assembly (22) is axially compressed between the shoulder (30) of piston rod (16) and the rod guide (18) until the elastomeric ring (24) deforms to abut the inner wall (64) of the working cylinder. As the elastomeric ring deforms, the annular chamber decreases in volume. A restrictive passage (71) allows a restrictive flow of fluid therefrom. An additional chamber (70) is formed which is in restrictive fluid communication through the passage (71) with section (68) of rebound chamber (20). Further compression of the stop assembly (22) decreases the volume of both chambers (70 and 74), and causes restrictive fluid flow out therefrom through the passage (71) into the section (68) of rebound chamber (20). The compression of the elastomeric ring and the restrictive fluid flow provides additional damping at the end of the rebound stroke.
    • 减震器(10)具有回弹止动组件(22)。 回弹挡块组件(22)位于固定在活塞杆(16)上的肩部(30)上。 回弹止动组件(22)包括介于两个套环(26和28)之间的弹性体环(24),其在它们之间形成环形室(74)。 在活塞杆(16)的回弹冲程结束时,回弹止动组件(22)在活塞杆(16)的肩部(30)和杆引导件(18)之间轴向压缩,直到弹性体环(24) 变形以邻接工作缸的内壁(64)。 当弹性体环变形时,环形室的体积减小。 限制通道(71)允许流体从中限制流动。 形成有与回弹室(20)的部分(68)通过通道(71)限制流体连通的附加室(7​​0)。 止动组件(22)的进一步的压缩减小了两个腔室(70和74)的体积,并且使限制流体从其通过通道(71)流出,进入回弹室(20)的部分(68)。 弹性环和限制流体流的压缩在回弹冲程结束时提供额外的阻尼。
