Sagwell customer case: Optimizing diamond tool matrix using iron-based alloy powder

In this article, Sagwell tells a customer case (customer information will be blurred). The customer is a mining tool segment manufacturer that usediron-based alloy powder to conduct optimization experiments on diamond tool matrix.

Mining blade are one of the core products of our customer. Last year, the customer came to us and hoped to extend the service life of the cutting blade without affecting the sharpness of the cutter heads. We asked the customer to send us the processed cutting blade first so that we could analyze the problem.

The formula of this cutting blade is mainly iron-based Alloy Powder. The current problem is that the cutting life is only XX meters, and diamond fall-off pits were found under microscopic observation.

Actual case:

Optimization solution for iron-based diamond tool blade

Initial question:

The life of a certain iron-based cutting blade when cutting sandstone is only XX meters, and the diamond falls off severely.

Experimental analysis:

SEM shows that the matrix porosity is relatively high (15%) and the diamond wrapping is not firm.

Wear tests showed that the blade hardness was insufficient (82 HRA).

Optimization measures:

1. Add 5% of Sagwell's iron-based alloy powder to improve hardness and wear resistance.
2. Use ultra-fine powder to reduce porosity.

Test results:

Porosity dropped to 8%, hardness increased to 86HRA, and service life increased to XXX meters.

The solution provided by Sagwell this time solved the life problem of diamond tool matrix for this customer. Customers who use iron-based alloy powder can consult us whether they need to improve sharpness or extend service life. You can also consult us for the specific data involved in the above case.
