Dana Corporation Awarded Patent for Plasma-Assisted Metal Joining Technology

    TOLEDO, Ohio, June 13 /PRNewswire-FirstCall/ -- Dana Corporation
(NYSE: DCN) announced today that it has been awarded the first patent for its
AtmoPlas(TM) microwave atmospheric plasma heating technology.  The patent is
for plasma-assisted joining of metal components.  A total of 20 patent
applications for AtmoPlas uses are pending in the United States.

    "This initial patent is the first step in bringing the AtmoPlas technology
and its multitude of uses to the heat-treating industry," said Chuck Heine,
president of Technology Development at Dana.  "Dana's AtmoPlas technology has
the potential to revolutionize heat treating by significantly reducing costs
and improving both efficiency and material properties."
    The key to the AtmoPlas technology is its ability to generate plasma at
atmospheric pressure without costly vacuum equipment.  The plasma harnesses
microwave energy to quickly generate temperatures up to 1,200 degrees Celsius
within seconds to efficiently join metal components.
    Major benefits include dramatically shorter cycle times, lower capital and
maintenance costs, and significant energy savings.  Microwave-absorbing plasma
utilizes 95 percent of the energy in microwaves to rapidly and reliably join
metal parts through brazing, welding, bonding, and soldering.  By absorbing
and focusing the microwaves, the plasma significantly reduces the possibility
of arching while evenly distributing the heat, reducing the potential of
thermal shock to metal components.
    "Dana's AtmoPlas technology shows our commitment to playing a central role
in developing revolutionary automotive and manufacturing technologies," said
Heinz-Ubbo Eilks, vice president of business development and technology at
Dana.  "As we move forward, Dana is exploring additional new and exciting
applications for this innovative technology."
    Dana is currently testing samples for brazing with its customers.  In
addition, future applications for AtmoPlas technology may include using
microwave energy to treat vehicle-exhaust gasses, generate hydrogen, and
create carbon nanostructures for use in the electronics and medical fields.
    Dana people design and manufacture products for every major vehicle
producer in the world.  Dana is focused on being an essential partner to
automotive, commercial, and off-highway vehicle customers, which collectively
produce more than 60 million vehicles every year.  A leading supplier of axle,
driveshaft, engine, frame, chassis, and transmission technologies, Dana
employs 46,000 people in 28 countries.  The company is based in Toledo, Ohio,
and reported sales of $9.1 billion in 2004.  Dana's Internet address
