Applying Carbide for Wear Surfacing and Gripping



For a large portion of the company's 83-year history, Rocklin Manufacturing Co. has manufactured and sold the Rocklinizer carbide application equipment. Through a proprietary electronic spark deposition process, the Rocklinizer deposits titanium carbide (80 Rockwell C), tungsten carbide (70 Rockwell C) and Rockhard electrode (60 Rockwell C) onto and underneath the surface of metals, tools and dies. "This process alleviates metal-on-metal wear, enhances gripping, maintains dimensions and ultimately extends the useful life of machinery to delay or even avoid new equipment purchases," said a company spokesperson.

The recently launched Rocklinizer Model 950 deposits as little as .0001" to .010" and higher onto the base material, all controllable within .0001" by a digital machine setting for a precise application. The lower deposits are suited for preventing slug pull in punching and stamping operations and extending the life of cutting edges and tooling. Medium deposits are best for restoring tolerances on bearings and shafts and for die casters seeking to prevent heat checking, soldering and seizing of cores. The higher settings combined with the Rockhard electrode produce a rough surface suited for gripping applications such as tube bending, collets, clamps, feed fingers and even forklifts and non-slip flooring.

As the electrode is deposited over the same area via the rotary applicator, the Rocklinizer is merely filling in gaps but not adding more materials to existing deposits. Only by changing the machine setting or the electrode type is additional wear-resistant material added. This feature results in a uniform coating.

Unlike welding, no appreciable heat is generated, and the electrode material will not separate or flake off of the workpiece. Once the process is completed, no heat treating, grinding or other surface treatment is necessary.

The new Model 950 offers a much faster application speed than previous Rocklinizer models, a feature that is designed for coating larger parts and dies. A five square inch coating takes less than 1 minute via high speed settings, while the process can be slowed for more delicate operations.

The company also offers an automation option for coating large areas in addition to the handheld rotary applicator. Furthermore, a continuous duty air pump is embedded inside the unit to deliver cooling at higher settings and ensure full portability of the 35 lb. unit.
