Background: A scientist at Hebrew University in Jerusalem has discovered a new process for chromium plating which is twice as twice as efficient as the old method. Chromium plating is widely used in industry, especially in aircraft design.

Professor Mark Perach, who migrated recently from the Soviet Union, developed the new process while working in the University's Graduate School of Applied Science and Technology.

He questioned the old rule, based on a solution of chromium trioxide and sulphuric acid, with one per cent acid, and suggested the possibility of getting just as good quality chrome plate under different conditions.

Normally about 85 per cent of the electrical energy used in the reduction process is wasted on the simultaneous release of hydrogen. Only 15 per cent of the energy actually goes into the chrome plating.

Using Prof. perach's method, about 32 per cent of the electrical energy goes into the chrome, and only 68 per cent is wasted.

The actual process is a commercial secret and has been registered for patent. Yissum, the university company which deals with the commercial use of university inventions is negotiating with several large industries, one in Israel, others in Europe and America for its adoption.

SYNOPSIS: Hebrew University in Jerusalem, where a new process for chromium plating has been discovered. Chromium plating is widely used in industry, especially the aircraft industry. here a laboratory assistant at the University tests the new process on copper plate. A scientist at the university, Professor Mark Perach developed the process after two years research. It is twice as efficient as the old method.

Normally an electrical current is passed through the metal dipped in a solution of chromium trioxide and one per cent sulphuric acid. About eighty five per cent of the electrical energy is wasted on the simultaneous release of hydrogen, while only fifteen per cent goes into the chrome plating.

But Professor Perach questioned the old rule and produced positive results. His process has been registered for patent and several large industries in Israel, Europe and America are negotiating to use it.
