MIDCO TBS® is an effective antiwear additive, by itself or in combination with other antiwear/EP additives. It contains no phosphorus, sulfur, or metals, and it is useful in eliminating and/or reducing levels of these elements in lubricants.

Falex® Pin and Vee Block Test data (Figures 1, 2 and 3) show that MIDCO TBS® affords antiwear protection not provided by other additives such as zinc dithiophosphate (ZDDP), ashless dithiophosphate (ADDP), zinc dithiocarbamate (ZnDTC), molybdenum dithiocarbamate (MoDTC), ashless dithiocarbamate (ADTC), and alkyl thiadiazole (ATD). The Falex Pin and Vee Block Test data (Figures 2 and 3) also show that MIDCO TBS® forms synergistic combinations with these additives.

 

 

Figure 1. The bar plot compares the antiwear performance of MIDCO TBS® with that of ZDDP. A 500 pound jaw load was applied to the standard steel vee-blocks and pin. The pin was rotated at 290 rpm for 60 minutes.  Under these test conditions, a FAIL rating is considered to be any test, which did not run for 60 minutes due to excessive wear or high torque. Mass loss is not relevant to FAIL ratings, and is therefore not provided.

 

Figure 2.  The bar plot compares the antiwear performance of single additives with and without MIDCO TBS®. A 500 pound jaw load of was applied to the standard steel vee-blocks and pin. The pin was rotated at 290 rpm for 60 minutes.  Under these test conditions, a FAIL rating is considered to be any test, which did not run for 60 minutes due to excessive wear or high torque.  Mass loss is not relevant to FAIL ratings, and is therefore not provided.

Figure 3.  The bar plot compares the antiwear performance of single additives with and without MIDCO TBS®. The additive combinations at 0.70 mass percent treat level outperformed the single additives at 1.0 mass percent treat level.  A 500 pound jaw load was applied to the standard steel vee-blocks and pin. The pin was rotated at 290 rpm for 60 minutes. Under these test conditions, a FAIL rating is considered to be any test, which did not run for 60 minutes due to excessive wear or high torque.  Mass loss is not relevant to FAIL ratings, and is therefore not provided.

An Optimol® High Frequency, Linear-Oscillation SRV® test machine demonstrates that more durable and lower friction antiwear films are formed when MIDCO TBS® is combined with other additives. At equivalent treat levels of 1.0 mass percent, lubricating compositions containing the additive combinations maintained lower friction coefficients for longer periods of time than lubricating compositions treated with single additives. The synergy between MIDCO TBS® and MIDCO POLYX® and that between MIDCO TBS® and ZDDP, is shown in Figures 4 and 5 respectively.

Figure 4. Test Parameters: 80 ºC; 50 N break-in load; 200 N test load; 50 Hz; 1.00 mm stroke; test duration of 120 minutes.

Figure 5. Test Parameters: 25ºC; 50 N break-in load; 1000 N test load; 50 Hz; 1.00 mm stroke. Experiments ran until failure as indicated by a large and sudden increase in the friction coefficients.
