Abstract: The influence of some commonly used inhibitors on the tungsten carbide leaching of the cemented carbide tool was studied by energy spectrum analysis and electrochemical gaging. And the mechanism of the tungsten carbide leaching and be inhibited of the cemented carbide was discussed. The test results showed that when cemented carbide tool were soaked in tri-sodium phosphate and sodium carbonate anhydrous the tungsten carbide in the cemented carbide tool leached out for hydration. And benzotriazole has a good inhibitory effect on the tungsten carbide leaching of the cemented carbide tool.

Abstract: Grinding tests and trials on production equipment is a most expensive proposition. The expense is not only with respect to the monetary cost, but also the down time associated with interrupting a production line to make special runs and set-ups. That high cost is generally the reason given why not to conduct production grinding tests. Testing is more easily justified in a laboratory environment, however the testing can become “clinical” such that it is far removed from the real world of production grinding and the results are often unrealistic. It has been the object of this project to target an industry and simulate, as closely as possible, a production grinding environment, in the laboratory, to encompass all of the realism of bearing production but with quick-changeover features that allow frequent and accurate adjustments to the process with respect to the set-up but moreover, the grinding fluid. The end result is test data that is meaningful, directly relevant, acceptable and understandable to the industry. It has also provided a platform for further investigative work with respect to the surface texture produced by certain fluid chemistries.
