We are a manufacturer of motor bikes. A part named "Swing arm" fitted in motor cycle has a sub assembly part named "Rubber bush rear fork pivot". This part is actually rubber & pipe bonded part, the pipes used in this part are parkerized.

here I wan to ask you ..... 1) what is the process condition for this part? (Please answer in detail) 2) do we use the same conditions as we used in our painted items? 3) what is the general testing standard for parkerizing? (SST , adhesion etc )

In relation to your part that's been "Parkerized". Parkerizing is the process of dipping a metal part into a Hot(305 degree) solution of a blackening agent, similar to what is used in a standard "Black" tank. Vehicle cam shafts are parkerized at times to prevent premature wear."Black" tank processing is also used for gun barrels to black or blue them. A parkerized coating isn't very useful when exposed to weather.

Have a good day,
