The Haval company conducted corrosion tests of a crossover produced at a plant in Russia; the tests correspond to 12 years of operation. For the tests, a production Haval Dargo car was used, which did not undergo any special training, said Alexey Komarov, deputy director of the quality management department at Haval Motor Manufacturing Rus, reports an Izvestia correspondent.
The test was carried out jointly with the specialized laboratory NAMI, it consisted of 127 accelerated cycles, each of which included placing the car in a salt chamber for six hours (3.5% NaCl solution) at a temperature of +37 degrees and a relative humidity of 95%. After the salt chamber, the car drove along a special route at a training ground 116 km long, which includes unpaved sections. Before and at the end of each cycle, the crossover was placed in a bath filled with a more concentrated 5% NaCl solution.
Before the test, specialists made lattice cuts to the surface of the metal (cutting through the zinc layer) in certain places on the body to test the ability of the paintwork's protective mechanism to resist corrosion.
“All 127 test cycles are equivalent to 12 years of vehicle operation in the conditions of Moscow and St. Petersburg. At the end of last week – the beginning of this week, all cycles were completed, the initial inspection showed that the car meets all our expectations. Now we are planning a further in-depth analysis, the car will be completely disassembled,” Komarov said.
Now cars at the Russian Haval plant undergo the same anti-corrosion treatment as in China. When asked whether any changes would be made to the production process based on the results of the test, Komarov replied: “Yes, if we find some points for growth.”
Earlier, Izvestia reported that Haval held the first demonstration of the operation of an engine plant in the Tula region. The plant produces turbocharged engines of 1.5 (150 hp) and 2.0 liters (192 hp), and five industrial manipulators are installed on the assembly line.
