Hard Chrome Service

Hard chrome plating already applied to many kind of part and use by many customers. Hard chrome process can be customize to the customer requirements and spect needed by customer. Different requirement of hard chrome may be vary because each of part have been used in different application that for some customer may need very high spect of hard chrome because of their application need that special treatment like in military plating specifications. Military requirement sometimes difficult to fulfill like chrome in long hollow material like pipe, because electroplating can’t plate in the long hollow. Chrome plating just can do on the near of the end edge of the pipe, this is may need special treatment and special tools to make chrome plating in the hollow pipe can do.

Hard chrome customer is very wide and very huge money turn on this business. Almost all Industry need hard chrome plating, tools steel is usually being chrome plated, every shaft of turning equipment is need to coat by hard chrome plating, every hydraulic of certain part big and small is need to coat by hard chrome plating in order can move with smooth and don’t leakage. This is very high market demand on hard chrome plating if you can catch them.

How to Create article Map

Article map is mean article content. Article content can help reader to read focus to certain topic. He/She don't need to read all content and just found what He/She need or looking for. Every blog reader will boring to read long, because your written is not interesting anymore. But he/she need to know something from your blog, so she/he come to your blog and read to find something.

For example this one is the blog navigation about electroplating process on my other blog: So what do you think, any other idea?

Adhesive Wood Glue

As in general wood adhesive can be made from melamine formaldehyde resin or from urea formaldehyde resin. Wood glue in general have termosetting characteristic this mean that this glue will changed their character from thermosetting when new but then changed to thermosetting when over their temperature or time. This limitation called as curing time. The form of urea formaldehyde as wood glue can be in powder or in paste depend on their packing.

Here is the picture of urea formaldehyde powder:

Steel Composition

The main contain of carbon steel is iron. In general, steel with a higher carbon content are hard and brittle, while steels with a lower carbon content are ductile and tough. Alloy component add to iron steel such as chromium, molybdenum, nickel, manganese, or silicon to increase corrosion resistance or attain a better balance between strength and toughness.

As in general contain of carbon steel between 0.12 to 2.00 percent of carbon. Other contain either of carbon can be 10.5 percent this steel is called as alloy steel. The general definition of carbon steel is mean that contain of high carbon or usually called as high carbon steel that is very hard, this steel have good abrasion resistance and retaining shape. This steel can withstand to significant tensile strength, high carbon steels are more likely to crack than bend.

Nickel Plating Bath Chemical Solution

Nickel plating bath chemical composition should be included of satin finished chemicals in order get a brighit surface after plating. Beside a nickel salt that usually use Nickel Sulfate, also contain of an alcohol soluble polyamide resin and polishing agent disolved in bath alltogether. The polyamide resin is a member selected from the group consisting of a copolymer of dimer acid and an aliphatic amine, a copolymerized nylon and a modified nylon. The electroplating bath preferably contains a cationic surface active agent selected from the group consisting of an aliphatic and/or aromatic quaternary ammonium salt and an aliphatic and/or aromatic fluorosulfonylamine quaternary ammonium salt. The use of the electroplating bath provides a means for obtaining a uniform satin-finish nickel plate surface on the material plated.

Chemicals plating solution of acidic nickel electroplating bath contain of a uniform satin finish metal plate surface on the material plate surface as below:

1. Nickel 25 to 170 gm/lt
2. Polyamide resin disolved in low molecularweight and alcohol have 1 to 3 carbon atom: 1 – 10,000 ppm
3. Polishing agent: 0.1 to 40 gm/lt

Nickel is dissolved and forms a continuous aqueous phase solution and polyamide resin is dispersed in aqueous phase to form a stable emulsion.
