[Case Study] Extending the lifespan of seal rings and oil seals with explosive thermal spraying!
Long lifespan of seal rings and oil seals with explosive thermal spraying!
In the roll shop (the department that maintains rolls), tasks such as grinding rolls, maintaining seal parts, and servicing grinding machines are performed. Iron seal rings and rubber oil seals are used for the roll grinding machine parts, and both of these components experience significant wear and have a short lifespan, leading to time-consuming and labor-intensive maintenance issues. Issues and Points 1. The oil seals are inexpensive and can be replaced regularly, so we want to extend the lifespan of the seal rings. 2. Since the seal rings themselves are not very expensive, we would like to implement cost-effective measures. The inability to insulate these two areas leads to heat dissipation and losses. 3. Various tests have been conducted in the past, including hard chrome plating, carburizing treatment, and Dycron plating, but the results have not been satisfactory. (Both wear out in a short period, or one has a longer lifespan while the other has a shorter lifespan, etc.)

basic information
We propose a wear-resistant, non-adhesive D-gun thermal spray and have arranged for the thermal spray material to be tested with tungsten carbide. Points: 1. Selected materials with better wear resistance than carburizing treatment and lower friction coefficients than Dykron plating (hard chrome plating). 2. Cost-effective options.
