Nickel release rate calculation results as shown in table 3 test results, even if it is the same raw materials, different nickel release rate significantly to production methods.
The calculated rate of nickel release. The test results are shown in Table 3, even if it is the same material, nickel emission rates vary significantly with production methods.
The calculation of release rate of nickel. As shown in the test results in Table 3 even the same raw material nickel release rate were significantly different with manufacturing methods.
